In spite of having remarkable changes in the formula of auto paints over the past couple of decades, only a few types of categories of the individual automotive paints are popular. When solvent-based paints have been avoided in waterborne or acrylic products due to safety regulations for workers and environmental concerns, following are the GI & Automotive coatings
which are classified for use:
Due to fast drying process and thin body, these paints flow smoothly. Lacquer-based finishes and paints can easily be sprayed and dried with gloss finish. Since these paints are thin, they provide very little UV resistance. Basically, these paints are coated on top surface with acrylic urethane in order to have a prolonged layer of protection.
From late 1950s to 1980s, acrylic lacquer was the most sought-after automobile paint and it was mostly on luxury and expensive vehicles like Rolls Royce. To complement such cars, it leaves glossy finish once dried. The best part is that it catches less dust and dirt as it dries faster. But you should buff it in order to have shiny finish for a very long time.
Due to heavier body, these paints are harder for application. These paints are subject to pool and develop an orange-peel impact after getting dry, if you apply a thick coat. As compared to lacquer-based paints, these paints dry slowly as they have a heavy body. If filtered air supply doesn’t exist in working area, they may receive lint, dust or other imperfections. But due to same heavy body, they deliver excellent performance. Along with metal flake, they are available in different styles.
Due to the rise of environmental concerns, the water-based acrylics, waterborne and urethane paints are developing faster. Out of them, waterborne paints are known as most versatile variety. You can apply waterborne enamels on primers or bare metal or present coatings. For DIY car finishers, these paints are safe and widely-known option to work from personal garage. With acrylic or waterborne urethane, these paints are coated on top surface for prolonged protection.
Paint Classification Systems
Out of several different categories, one can separate these paints in classifications. These systems are used to individualize paint in single-stage, undercoat, mid-stage, clear-coat and base-coat products. With these systems, automobile paints are classified into usage instead of composition in the process of painting.
These paints are known for their heavy-body base and they last longer than enamel or lacquer based paints. These paints are usually applied on engine parts and those parts which receive high temperature. There are 2 components on such paints, in the paint, you can add a catalyst to increase the process of drying. They create wet gloss finish and solid shell finish once dried.
As compared to lacquer based paints, lesser coats of 2-pack paint products have to be applied. It is durable and long-lasting too. It delivers appealing shine and finish which requires no maintenance and no buffing and sanding. But for expensive cars, it is a bad choice as it gives plastic or artificial look to the vehicle.
