YWU4130 tetra-functional aliphatic urethane acrylate resin oligomer having a molecular weight of 650 - Between 1500 and moderate molecular functional groups, both toughness and crosslinking moderate, strong bonding, exhibits excellent macroscopic properties of the material, such as excellent toughness and hardness, high gloss, yellowing resistance and chemical resistance, since the main functional group-containing acrylic double bonds, radiation curable or chemically cross-linked products with light color transparent, balanced flexibility and hardness, scratch resistance, non-yellowing high-gloss wide range of applications, can be used alone as a binder for UV light curable coatings, inks and adhesives and other products, but also systems and other acrylic, epoxy, polyurethane, nitro and other materials blended material for improving adhesion; change and crosslinking hardness, adhesion strength and resistance to yellowing transparency have a significant effect.
