China's first floor paint binders mainly composed of resin, its type is as follows:
(1) polyurethane resin: it is made of isocyanate with polyester, polyether, epoxy resin, castor oil and its processing products containing hydroxyl thermoplastic polymers such as cellulose acetate butyrate formula, made into many kinds of polyurethane coating. Such as TDI and MDI and polyether with is the first basic material of elastic coating on the ground; HDI and polyacrylic acid resin containing B hydroxyethyl blending, is the basic material of high-grade floor coating.
(2) the epoxy floor paint grease used for floor coating, often with low molecular weight polyamide resin curing, the epoxy resin on the floor with a seamless coating material on the ground, the other type of exterior wall coating first base.
2 must be film-forming substances
Must not film-forming material also is the main form of coating is local, but it means less separate primary film forming substance alone into a film. This component is used in coating for paint.
