Polyurethane acrylate

Polyurethane acrylate is composed of a plurality of isocyanate, polyol and acrylic light radical reaction and preparation. Through proper coordination of rigid flexible polyisocyanate andpolyether chain segment, the performance of different resin can be obtained. The product can be very hard state can also be elastic and very soft state. Polyurethane acrylate resin withpolyurethane flexibility (especially the low temperature toughness), wear resistance, aging resistance and high tear strength

The C=C key and a polythiol change polyene -SH equivalence ratio, the number of functional groups or multiple olefin and multiple thiols in molecules, can be obtained from the curedelastomers to resinous variety of morphological. When creating the application of polycarboxylic acid and the reaction of allyl alcohol ester, unsaturated compound to produce carboxylic acidand polyol ester and polyene and multiple thiol containing ester bond as the main component ofmercaptan polyene systems photocurable resin, in wet conditions, the solidified products tend to be hydrolyzed, resulting in reduced adhesion strength three: while the application of allylisocyanurate as light curable composition, cured was soft, elastic, good transparency andmoisture resistant cured. This system is not affected by the oxygen in the air of polymerization,and the curing shrinkage of small, multi use sub communication device, optical device assemblyand fiber bonding.
