The molecules of a binder are made of polymer combinations. The convertible binder is made of materials used in an unpartial polymerized state. After the application of a substrate, they undergo a reaction to make a film that is solid. Oil paints, Oleoresins varnishes, and silicone resins are among some of the convertible binders. The nonconvertible binder is a polymerized material that is dissolved in a medium and which evaporates after a coating has been included.
Acrylic paints, and vinyl polymers are among some nonconvertible binders.
The evaporation rate for nonconvertible paints is a critical factor in paint quality. If the evaporation is slow, then problems occur in the coating application as well as excessive flow of the wet paint. If the evaporation is fast, it could affect the flow and integrity of the paint. For paints with slow evaporation, brush application is commonly used, and for high evaporation spraying should be used. The second component in paint is the solvent.
