China University of technology develops dual curing polyurethane wood coating

March 12, 2013

[China coating information] recently, South China University of technology developed (9) if necessary, successfully developed a moisture and UV dual curing polyurethane wood coating

this new coating is mainly made of aliphatic diisocyanate, diol prepolymer, polyhydroxycarboxylic acid, epoxy resin, hydroxyacrylate and other raw materials, and added with photoinitiator, leveling agent, defoamer, substrate wetting agent, catalyst and other additives

the coating developed by this project can form a film and cure under UV irradiation, and can also be cured by moisture in the air within 5 hours at room temperature. It has the advantages of high solid content, high NCO group content, high adhesion, good chemical corrosion resistance, high film hardness and good storage stability. 2 Spring fatigue testing machine: it is an engine that controls the operation of the components of the spring fatigue testing machine. It can be used for irregular coating surfaces that cannot be exposed to ultraviolet light, matte UV paint, UV color paint, etc. the development space and ecological environment of the enterprise are relatively improved
