What is the name of the paint that is applied after primer?
Base Coat. The base coat is applied after the primer coat. This coat contains the visual properties of color and effects, and is usually the one referred to as the paint. Base coat used in automotive applications is commonly divided into three categories: solid, metallic, and pearlescent pigments.

What is pearlescent paint?
Pearlescent paints contain special iridescent pigments commonly referred to as "pearls". Pearl pigments impart a colored sparkle to the finish which works to create depth of color. Pearlescent paints can be two stage in nature (pearl base color + clear) or 3 stage in nature (basecoat + pearl mid-coat + clear-coat).
What is metallic basecoat?
Metallic basecoats are formulated so that the aluminium flake is parallel to the substrate. This maximises the "flop". This is the difference in the brightness between looking perpendicularly at the paint and that at an acute angle.
What type of paint has no sparkle?
Solid paints have no sparkle effects except the color. This is the easiest type of paint to apply, and the most common type of paint for heavy transportation vehicles, construction equipment and aircraft. It is also widely used on cars, trucks, and motorcycles.
Why do we need phosphate coat?
A phosphate coat is necessary to protect the body against corrosion effects and prepares the surface for the E-Coat. The body is dipped into the Electro-Coat Paint Operation (ELPO/E-Coat), then a high voltage is applied. The body works as a cathode and the paint as an anode sticking on the body surface. It is an eco-friendly painting process.
What are the ingredients in paint?
The Basics All paints are made up of three ingredients: binder, pigment, and a carrier agent. Pigment, or tint, is self-explanatory-it's the color you see. Binder is often referred to as resin, and it can be helpful to think of it like tree sap, that thick, sticky hydrocarbon liquid that hardens when exposed to air.
What is the chemical compound that keeps paint resin in liquid form?
Automotive paint resins are usually one of the following three chemical compounds: lacquer, enamel, or urethane.
Is lacquer good for a show car?
Those liquid portions are highly toxic solvents like toluene that don't react well with Green Party members. So lacquer is great for a show car that spends 90 percent of its life in a climate-controlled garage, but not practical on a driver. That leaves enamels and urethanes as the remaining options.
Is enamel a better resin than urethane?
Seeking clarity, we spoke to some industry insiders about the differences between these two compounds, and all were in agreement: Enamels are a softer resin, usually dry to a glossy finish, and are less expensive than urethanes.

Is paint solvent based?

When was synthetic enamel invented?
In 1929 , synthol, alkyd or synthetic enamel was introduced. This paint system provided a harder, more durable surface. Synthol enamels used enamel reducer and a hardener to speed the drying time. Synthol paints dry initially as a lacquer but a chemical reaction hardens the paint film to dry it further.
What are the benefits of acrylic enamel?
The benefits of acrylic enamel were durability and that clear coat was not needed. In the early 1980s, polyurethane enamels were developed. Polyurethanes feature a very hard surface and were initially developed for non-automotive uses such as aircraft. Polyurethanes also use their own enamel reducers and hardeners.
When did water based paints start?

Following some basic rules for the type of paint you are using will go a long way toward ensuring that your paint job will come out the way you envisioned it.
Paint Stages
The first thing to understand is that most automotive paint is broken down into two main categories according to the number of “stages” involved in the paint job.

Paint types

What is Lacquer Paint?

What is Enamel Paint?
Enamel paints are often broken down into two additional categories - Synthetic Enamel, and Acrylic Enamel Synthetic Enamel should be thought of as a Utility Grade Paint. It’s usually only available in basic premixed colours, and is often used in situations where the paint doesn’t need to last too long, or won’t be exposed to a hard life.
What is Urethane Paint?
Urethane finishes are probably the best commercially available paint choice currently, and are available in any colour you could require.
What is Epoxy Paint?
These aren’t usually used on cars but are great for vehicles (or parts) that require an extremely durable finish. These paints are usually sold as rust prevention or protection from acids or other corrosive substances. Most epoxy paints are incredibly toxic, so appropriate protection should be used, or you’ll probably die.
What is Powder Coating?
This is a special process that requires baking a kind of plastic dust onto statically charged metal. It’s not used on exterior finishes usually (it’d be a massive job!) but Is very commonly used on small parts that need a durable finish, or on wheels and the like.
Overview
Automotive paint is paint used on automobiles for both protective and decorative purposes. Water-based acrylic polyurethane enamel paint is currently the most widely used paint for reasons including reducing paint's environmental impact.
Modern automobile paint is applied in several layers, with a total thickness of around 100 µm(0.1mm). Paint application requires preparation and primer ste…
History
In the early days of the automobile industry, paint was applied manually and dried for weeks at room temperature because it was a single component paint that dried by solvent evaporation. As mass production of cars made the process untenable, paint began to be dried in ovens. Nowadays, two-component (catalyzed) paint is usually applied by robotic arms and cures in just a few hours either at room temperature or in heated booths.
Processes and coatings
High-pressure water spray jets are directed to the body. Without proper pretreatment, premature failure of the finish system can almost be guaranteed. A phosphate coat is necessary to protect the body against corrosion effects and prepares the surface for the E-Coat.
The body is dipped into the Electro-Coat Paint Operation (ELPO/E-Coat), then …
Terminology
The terminology for automotive paints has been driven by the progression of technologies and by the desire to both distinguish new technologies and relate to previous technologies for the same purpose. Modern car paints are nearly always an acrylic polyurethane "enamel" with a pigmented basecoat and a clear topcoat. It may be described as "acrylic", "acrylic enamel", "urethane", etc. and the clearcoat in particular may be described as a lacquer. True lacquers and acrylic lacquers are o…
Chemistry
Modern car paint is typically a made from acrylic-polyurethane hybrid dispersions, which are a combination of two different plastics. They were developed during the 1970's and 80's as a water-soluble replacement for enamel paints, following health concerns over their high VOC content. Acrylic is less expensive and can hold more pigment, but has poor scratch resistance, whereas polyurethanes are harder but more costly. Combining both types gives a material which can con…
Types and Form
Innovations are taking place in paint industry as well. These days, automotive paints come in liquid form, spray form, and powder forms:-
• Liquid: Usually polyurethane paints. Compressor is needed to apply.
