Learn How to Properly Apply Gel Coat

Learn How to Properly Apply Gel Coat Applying gel coat correctly is of utmost importance to making aesthetically pleasing and long-lasting end products. If gel coat is not applied properly it ultimately can increase the cost of the product made, as often is the case, cutting corners in this process will not prove to be worth it. How Do Improperly Applied Gel Coats Increase Cost? It depends on a number of parts that get rejected and the work required to fix them. The amount of work and material saved by investing in a proper gel coat application process will pay off in the end. Proper gel coat application includes: Material preparationEquipment calibrationUse of trained spray operatorsAppropriate spray methods Gel coats should be sprayed and not brushed. The equipment used for spraying must be selected carefully and maintained well. Catalyst levels are important to the curing of the gel coat and dependent upon shop conditions. Most gel coats’ ideal catalyst level is 1.8 percent at 77Â °F (25Â °C), however, specific shop conditions may require this number to vary between 1.2 and 3 percent. Environmental factors that may require an adjustment in catalyst levels are: TemperatureHumidityMaterial ageCatalyst brand or type A catalyst level below 1.2 percent or above 3 percent should not be used because the cure of the gel coated can be affected permanently. Product data sheets can give specific catalyst recommendations. There are many catalysts for use in resins and gel coats. Proper catalyst selection is vital. In gel coats, only MEKP-based catalysts should be used. The three active ingredients in a MEKP-based catalyst are: Hydrogen peroxideMEKP monomerMEKP dimmer Each component helps the curing of unsaturated polyesters. The following is each chemical’s specific role: Hydrogen peroxide: starts gelation phase, though does little for a cureMEKP monomer: plays roles in initial cure and overall cureMEKP dimer: active during file cure stage of polymerization, high MEKP dimer typically causes porosity (air entrapping) in gel coats Achieving the correct thickness of a gel coat is imperative as well. A gel coat should be sprayed in three passes for a total wet film thickness of 18 /- 2 mils thickness. Too thin a coating can result in undercure of the gel coat. Too thick a coat can crack when flexed. Spraying gel coat onto vertical surfaces will not cause sag because of its’ thixotropic characteristics. Gel coats will also not entrap air when applied according to instructions. Lamination With all other factors normal, gel coats are ready for laminating within 45 to 60 minutes after catalyzation. The time is dependent upon: TemperatureHumidityCatalyst typeCatalyst concentrationAir movement A slowing of gel and cure occurs with low temperatures, low catalyst concentrations, and high humidity. To test whether a gel coat is ready for lamination touch the film at the lowest part of the mold. It is ready if no material transfers. Always monitor equipment and application procedures to ensure proper application and cure of the gel coat. Material Preparation Gel coat materials come as complete products and not other materials other than catalysts should be added. For product consistency, gel coats should be mixed for 10 minutes before use. Agitation should be enough to allow the product to move all the way to the container walls while preventing as much turbulence as possible. It is imperative not to over-mix. This can decrease thixotropy, which increases sag. Overmixing may also result in styrene loss that can add to porosity. Air bubbling for mixing is not advised. It is ineffective and adds for potential water or oil contamination.

The Translation of Photographic Images Into Painting Essay

The Translation of Photographic Images Into Painting - Essay Example The essay "The Translation of Photographic Images Into Painting" discusses what actually changed the set views and paradigms of artist of coming centuries was the ability to think out of the box. Such artists have given art a new dimension every time. Artists create art to communicate ideas, thoughts and feelings. They use a variety of methods such as painting, sculpting or illustration and an assortment of materials including oils, watercolours, acrylics, pastels, pencils. Artists, works may be realistic or abstract and may depict objects, people, nature or events. We are swamped by so many images, on the streets, in magazines and on the television. Artists usually create landscape paintings in one of four ways: They paint entirely on location; they rely on memory or imagination; they work from photos; or they use a combination of these source. Working from photos to create art pieces as paintings has always been an act which came under darkness due to overlapping views (and counter views too) about ethics of the profession and such other reasons. Some can say that painting taking initial source as a photograph lacks the freshness of thought and the as-it-is natural conditions. Too much reliance on photographs can result in paintings that lack breadth and are broken apart by tedious detail. But using a photograph as a mere source of reference to an idea is not discouraged at all. Rather it is very much beneficial in cases where there is no possibility of carrying painting equipment. or where there is short time between events that change the condition of the idea which has to be captured. Thus we look into the lives of various artists of mainly the twentieth century who have contributed their paintings with criticisms rolling off their backs and the praises not lowering their further elevation of imaginative journeys. "I remember the first place I went to on this trip where we were active, one of the resettlements that we built. I found that as far as I was concerned, they were impossible to photograph. Neat little rows of houses. This wasn't my idea of something fun to photograph at all. But I had the good luck to ask someone, "Where are you all from Where did they bring you from" And when he told me, I went on to a place called Scott's Run, and there it began. From there I went all through Kentucky, West Virginia, down to Arkansas, Mississippi, and Louisiana-in other words, I covered the mine country and the cotton country. I was terribly excited about it, and did no painting at all in that time. This was it, I thought. I'm sort of a single track guy, anyway. When I'm off on photography, photography is it, and I thought this would be the career for the rest of my life."1 The deep interpretative question in Richter's art concerns less the fact that he worked with photographs than why he selected the photographs he did for Atlas, and what governed his decision to translate certain of them into paintings. There are, for example, photographs of American airplanes-Mustang Squadrons, Bombers and Phantom Interceptor planes in ghostly gray-in-gray formations. Richter was an adolescent in 1945, and lived with his family within earshot of Dresden at the time of the massive fire bombings of that year. The photograph from which Bombers was made had to have been taken as a documentary image by some official Air Force photographer, whether over Dresden or some other city. The cool of that

Visual Arts Experimental Drawing - Research Project Paper

Visual Arts Experimental Drawing - Project - Research Paper Example Hopper first attended New York School of Art and Design, where he was shocked at the prospect of drawing live nudes. His choice of subjects was mostly boats and women, still life and natural landscapes. He was influenced by Manet and Degas and particularly loved Rembrandt’s use of light and dark shadows in Nightwatch, and the work of French engraver Charles Meryon. He hated illustrations but was forced by economic circumstances to work at a copywriting agency during his early professional life. After his father died he moved to and lived in his Washington Square apartment in New York’s Greenwich Village for the rest of his life (Kuh, 53). Hopper got his subject matter from both seascapes and landscapes and scenes in contemporary American life. His Girl at a Sewing Machine (1921) shows a girl at work on this machine, deeply involved as the sunlight comes into her room and lights it up. His work often depicts the solitude he felt in life. Hopper’s most celebrated p ainting is Nighthawks (1942) which is famous for its attention to detail, cinematic perspective and use of electric light set against the contrast of the night outside. It shows a group of people at a diner. Hopper’s Girlie Show (1941) is one of his more audacious pieces, where a red headed striptease is seen moving confidently across a stage as musicians play in the background (Barbara, 158).

She first studied at the Universite de Paris-Sorbonne in 1977–78 for a short while before moving on to Lond on’s St Martin's School of Art in 1978–79. She completed her art studies at the University of London, UK from 1979 to 1982. Lisa’s first solo art exhibition took place in 1984. She was also given the 1989 John Moore Painting Prize. Lisa currently teaches at the Slade School of Fine Art in London. As an artist, Lisa Milroy is famous for painting everyday items like vases, clothes and shoes in the form of collections. Milroy also paints objects in formations like in the shape of grids, lines, groups, rows and columns which she likes to create on plain backgrounds. Quite often Lisa’s arrangements of objects are influenced by their functional identity. For instance, stamps transform into islands for the eyes to travel between or wheels move forward at a dizzying visual pace. Handles (1989) won for Lisa the John Moores Award. This is a depiction of various handles of different types all spaced evenly through the work and can be viewed as a combination of lines dots and circles, assembled or spaced as in a catalog. The lack of color is intriguing and one cannot help wanting to pull on the handles to see if they work (Walker Art Gallery). Handles, 1989. Her painting Shoes (1985) shows a collection of shoes evenly spaced but in different configurations as to positions. Not one is repeated, they all

The Stranger Literary Responce Essay Example for Free

The Stranger Literary Responce Essay In a modern society people are often quick to judge others for being indifferent and making bad choices that they overlook the similarities between themselves and the person(s) being accused. A quote states, â€Å"The society Meursault lives in is as indifferent, as insensitive, and as moral as Meursault himself.† I agree with this quote because in the novel â€Å"The Stranger† by Albert Camus, Meursault plays a role in indirectly showing the reader through his natural actions of stoicism in his personality how society is not much different, indifferent. Meursalt acts as a mirror to society revealing in for how it truly is un-thoughtful and insensitive. The major points that have been often reoccurring throughout the novel are how indifferent and amoral Meursault is when it is shown that the society is in no form any better or more just. Throughout the novel Meursault is constantly displayed as a stoic individual who can endure pain or hardship without showing their feelings or complaining. Meursault’s character is often brought into question by those who contact and observe him. It is introduced to the reader at the very beginning of the novel that his mother, â€Å"Maman† had died and that his demeanor was unmoved. Meursault mentions how he can only register physical necessities of life meaning that he is emotionally detached which leads to his own demise. However, society views Meursalt as a terrible person because it is generally unnatural for a man, more less a human being to feel or express little to no remorse for their mother dying. Arguably Meursault is a cold hearted killer who would easily murder someone without any hesitation and no sense of remorse, using the fact that he killed an Arab to back this claim. However, he is not as cruel as society is. First off, the society does not treat Meursault with an equal respect or a caring attitude. Though Meursault has committed murder and was charged for insensitivity the society in The Stranger overlooks everything else basically including Meursault himself as other offenses are belittled will Meurault is almost automatically sentenced to death.

Man Against God in Nathaniel Hawthornes Rappaccinis Daughter Essay

Man Against God in Nathaniel Hawthorne's Rappaccini's Daughter In the introduction of the story, Nathaniel Hawthorne describes himself as a writer trapped between two worlds.   His alias, Aubepine, presents abstract concepts that would challenge the simple mind, but compensates for this by designing a dual meaning.   His works contain the literal meaning, and the implicated meaning.   Often, he would have to sacrifice his initial concept by injecting humor or other banal dimensions to the story in order to satisfy the lesser audience.   In this story, a young man from Southern Italy becomes implicated in a scientist's bizarre practice.   Rappaccini sacrifices his daughter's life in the name of science.   His means would resemble black magic in a different timeframe, which trespass the boundaries that man is ideally confined to.     Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Beatrice is the unfortunate and unwilling subject of her father's experiment.   The daughter's name is an allusion to Dante's guide in Heaven, and his wife in real life.   In the prelapsarian part of this story, the woman grows to know Giovanni ...

Supersize me Essay

In the documentary Supervise Me, Morgan Spurious embarks on a Journey to eat McDonald's fast food for every meal for an entire month. One of the main reasons for choosing McDonald's Is that this company represents 43% of the entire fast food market. There are a few rules, including that he has to eat every Item on the menu at least once and If they ask to supervise the meal, he must say yes. The purpose for this experiment was to see if fast food companies are too blame for the obesity epidemic going on in America right now.Some don't agree that obesity is that big of a deal, but sixty percent of Americans are either overweight or obese. I would call that a major issue. The fast food industry is most definitely partially to blame for obesity in the United States. Some people believe that it is not the companies' faults that people are becoming obese because that person chose to eat fast food. In a way, I do agree. But it is the fast food companies' responsibilities to make It known h ow unhealthy the food they are serving Is. To burn off a superseded Coke, fry, and Big Mac, you would eve to walk for seven hours straight.In addition, Spurious found that most McDonald's around the country did not have nutrition facts available for reference In the restaurant. Morality plays a major part in this issue. The Catholic Social Teaching of life and dignity of the human person is what is at stake. For every child born in the year 2000, one third will develop diabetes. This will cut anywhere from seventeen to twenty- seven years off your life. During the documentary, Spurious loses muscle and replaces it with fat because of all of the Junk he is putting in his body.His blood pressure was raised, and he was at stake of getting seriously ill. If a person eats too much fast food, they will become sick. It is very possible for an obsession with fast food to lead to obesity, which is linked to many other fatal diseases. A person's life may be at stake, which Is not morally righ t. In 2010, the Supreme Court ruled that corporations are viewed as Individuals. Therefore, they have the right to express their pollen, advertise to anyone they please, and have total control over their business. The average child sees 10,000 TV DSL per year.This means that companies are talking to children just as much, if not more than, their parents. If they were responsible with this power, then I would not have a problem with it. I think that there is a line between selling a product and doing whatever it takes to sell a product. If a company, like McDonald's, was appropriate in their advertising and kept the dignity of people in mind, then I don't think obesity would be a major issue anymore. This ties in with the Catholic Social Teaching of rights and responsibilities.In conclusion, I think that the fast food Industry Is partially to blame for obesity In the united States. Everyone does have a responsibility for their own health, but fast food companies have their own respon sibilities. They have the responsibility to make the Ingredients In their food known, and have healthy options. We as a country should hold them to this responsibility. With obesity rates rising, it could soon be the to our bodies and the fast food industry needs to realize that they need to do a better job of helping obesity rates decline.

Casual Analysis Essay Obesity Essay - 1367 Words

Casual Analysis Essay: Obesity There is an ongoing problem in the United States. According to the â€Å"Associated Press† this all began during the 1980’s and has got increasingly worse, especially in children. For children the obesity percentage has tripled and for adults it has doubled. The â€Å"Centers for Disease Control and Prevention† tells us that there are 97 million obese adults. This number is expected to increase by over 42 percent by 2030. If a persons body weights is 30% or higher then he or she is considered obese. The leading causes of obesity include fast food restaurants, portion sizes, lack of exercise, and medical reasons. Obesity in America is an epidemic, but in most cases it is avoidable.
