What effect does resin have in paint
A, how about resin paint
Epoxy resin paint is a coating with epoxy resin as the primary film-forming substance. There are many kinds and each has its own characteristics. There are self-drying single component, two component and multi-component liquid epoxy coatings by curing method. Baking type one component, two component liquid epoxy coating; Powder epoxy coating Cured epoxy coating. There are solvent - based epoxy coatings, solvent-free epoxy coatings and water-based epoxy coatings.
General characteristics are: strong adhesion, chemical resistance, corrosion resistance, water resistance, thermal stability and electrical insulation widely used in construction, chemical industry, automobile, ship, electrical insulation and other aspects. The paint will lose light and powdery after exposure to the sun in the field, so it is advisable to use as a primer.
1. Strong adhesion
Epoxy resin contains hydroxyl and ether bond and other polar groups, so that the resin and adjacent interface molecules effect is strong, some can also form chemical bonds, so its bonding strength is strong.
2. Good chemical resistance
Cured epoxy resins contain stable benzene rings and generally have good acid, alkali and organic solvent resistance.
3. Small shortening force
There is no by-product between epoxy resin and curing agent, so the shortening force is small.
4 .Good electrical insulation
The electric insulation of cured epoxy resin is better.
5. Good stability
Epoxy resin without curing agent, will not be heat cured, will not decay, good stability.
Two, resin in the paint what effect
Resin is the film forming material, is the more important component and the base, also known as the base material, it is the primary factor in the resolution of the film properties. Its function is to combine pigments and fillers together, and form a uniform fine film on the substrate, and form a coating after curing. Film forming resin is the base of coating, it determines the coating resistance, adhesion to the
