Product Introduction
YWU2921J is a two-component aliphatic polyurethane acrylic resin polymer with a molecular weight ranging from 4550 to 6600. It has a low molecular functionality, a small curing shrinkage, excellent adhesion and flexibility, and good weather resistance, acid and alkali resistance, good adhesion, high elongation rate, and exhibits excellent macroscopic properties such as excellent adhesion and resilience, high gloss, excellent color stability, weather resistance and chemical resistance. Due to the presence of acrylate double bonds in the main functional groups, it can be radiation-cured or chemically cross-linked. The product is colorless and transparent, has high adhesion and scratch resistance, high gloss without yellowing; it has a wide range of applications and can be used alone as the main resin for UV pressure-sensitive adhesives, UV adhesives for plastics and metals, PET films, OPP film screen printing inks, and can also be used as UV electronic sealants and other products. 

Application scope and recommendations:
Plastic topcoat primer, topcoat resin, UV pressure-sensitive adhesive as the main resin, with a content of 25-60% 
UV adhesive resin, used for bonding plastics and metals, bonding of PET, OPP films and other products, dosage 30 - 60% 
Electronics, cosmetics, furniture cabinet boards with UV spray finish and gloss treatment, dilution ratio 10 - 25% 
Screen printing ink, with excellent adhesion and gloss, with a concentration of 30 - 60% 
Other polymer adhesion and toughness modifiers, with a dosage of 10 - 30%
