Coating classification: polyester oil polyurethane coating

It is suggested that polyurethane coating with urethane oil is a kind of air dry coating, which is similar to alkyd resin, which is prepared by transesterification of dry oil with polyol, reaction with diisocyanate (TDI in common use), adding catalyst such as cobalt, lead and manganese epoxide, and drying in air with unsaturated bond of oil Polyurethane oil does not contain free isocyanate Compared with other polyurethane coatings, urethane oil polyurethane coatings have good acid resistance, good stability, convenient construction, long time limit and low cost, but they have poor alkali resistance, corrosion resistance, luster, drying time, wear resistance, hardness and other aspects, poor leveling, and use aromatic diisocyanate Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Home of coatings: Polyurethane Coatings with urethane oil belong to air dry coatings It is a kind of coating with similar alkyd resin performance, which is transesterified by dry oil and polyol, reacted with diisocyanate (TDI in common use), added with cobalt, lead, manganese and other catalysts of epoxy acid, and dried in air with unsaturated bond of oil Polyurethane oil does not contain free isocyanate Compared with other polyurethane coatings, urethane oil polyurethane coatings have good acid resistance, good stability, convenient construction, long time limit and low cost, but the alkali resistance, corrosion resistance, luster, drying time, wear resistance, hardness and other aspects are not good, the leveling is poor, and the urethane oil coatings with aromatic diisocyanate are prone to yellowing Compared with alkyd resin, urethane oil paint has the advantages of fast drying speed, good hardness, luster, fullness, wear resistance, water resistance and weak alkaline resistance, but poor weather resistance and yellowing more easily Urethane oil polyester coating belongs to one component polyurethane coating Polyurethane oil polyester coating is mainly used for general atmospheric protection, such as indoor furniture, floor, cement, ships, etc Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
