YWU2704 are di-functional acrylated polyester resin oligomer having a molecular weight of 2000 - Between 4000, low molecular functionality, excellent adhesion and flexibility, and containing adhesion promoting groups, strong adhesion, good impact resistance, exhibit excellent macroscopic properties of materials, such as excellent adhesion and toughness, high gloss, yellowing resistance, water resistance and chemical resistance, since the main functional group-containing acrylic double bonds, radiation curable or chemically cross-linked products light color transparent, high adhesion scratch resistance, high gloss non-yellowing; wide range of applications, can be used alone as a binder for UV light curable coatings, UV glue, PET, PMMA, PP film inks and adhesives, and other glass products, but also systems and other acrylic, epoxy, polyurethane, and other materials blended nitro, attached to the surface of the material for improving toughness and bonding strength and chemical resistance has a significant effect.
Plastic vacuum plating finish, the coating resin as the main resin content 15-40%
UV adhesives, and other acrylic, epoxy, urethane blends, for metal, glass, PET and other plastic products, content 10-40%
Electronics, cosmetics, furniture cabinets board UV varnish injection, by adding 10 - 30%
Screen printing inks, good adhesion and flexibility, content 10-40%
Other polymer adhesion and toughness modifier content 10-30%
