Insulating paint is the main component of the base resin, that is, film-forming material, is also the main material of insulating paint is to determine the performance of insulating paint good or bad key material, so according to its base resin classification polyester paint, Polyurethane paint, polyamide imide paint.
The base material is generally a polyester resin, polyester imide resin, polyurethane, epoxy resin, bismaleimide resin, silicone resin and other resin composition. Flame retardants are divided into reactive flame retardant and additive flame retardant; according to the composition can be divided into inorganic flame retardants and organic flame retardant. The purpose of adding pigments and fillers in coatings is to improve the properties of the coating and to prepare the desired color. Commonly used pigments and fillers are titanium dioxide, iron oxide red, carbon black, chrome yellow, mica powder, talc, barium sulfate, calcium carbonate and silica. Curing agent is an indispensable component of most insulating coatings. In the epoxy resin as the base of the flame retardant coating, must be added amine adducts, anhydride derivatives and synthetic resin curing agent; in the vinyl resin based flame retardant coating, should add the appropriate amount of peroxide As an initiator. Additives are insulating coating manufacturing, storage, construction and improvement of performance is one of the indispensable components, is the auxiliary ingredients of raw materials. It plays a special effect in the coating, the formation of the base film coating process and durability plays a very important role.
