General knowledge of coating: formula of two-component polyurethane elastic coating

It is suggested that the flexible polyurethane can be made into a soft coating with excellent hand feel, and it is a low crosslinking density system with linear molecular structure, which has high flexibility and elasticity, and endows the coating with excellent wear resistance, impact resistance and elongation The two-component polyurethane elastic coating is made of linear polyester resin containing hydroxyl as the main film-forming material, crosslinked and solidified with HDI type curing agent, and added with various pigments, fillers, additives, solvents, etc Choosing linear saturated polyester resin with hydroxyl group and micro branched saturated polyester resin with hydroxyl group to mix according to different proportion can ensure that the coating can reach one Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Home of coatings: elastic polyurethane can be made into soft coating with excellent hand feel, and it is a low cross-linking density system with linear molecular structure, with high flexibility and elasticity, giving the coating excellent wear resistance, impact resistance and elongation The two-component polyurethane elastic coating is made of linear polyester resin containing hydroxyl as the main film-forming material, crosslinked and solidified with HDI type curing agent, and added with various pigments, fillers, additives, solvents, etc Choosing linear saturated polyester resin with hydroxyl group and micro branched saturated polyester resin with hydroxyl group to mix in different proportion can not only ensure the elasticity and feel of the coating, but also maintain the rigidity, luster and adhesion This paper introduces the formulation of a two-component polyurethane elastic coating (see Table 1) 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,
