Basic composition of paints
Resin
Also called vehicle, it functions as a liquid support for the pigment. It is responsible for the adherence of the paint to the surface. The resin determines the type of paint (Polyester Base, Polyurethane Enamel, Nitrocellulose and Synthetic).
Pigment
A solid substance, finely ground (in the form of powder), is dispersed in the resin, which provides to the dry fim certain characteristics such as color, opacity, covering and protection.
Pigments with anti-corrosive properties
These are present in the composition of base paints (primers). They have the property of blocking rust.
Additive
Additive is added to paint in small amounts to provide it with special properties such as spread, shine, etc. Additives also have the function to avoid problems with bubbles, craters (fish eye), etc.
Solvent
Used for binding (mixture) of the pigment to the resin. It controls viscosity, spread and application. The film is formed after their evaporation.
