Product introduction

     YWU2570 are di-functional urethane acrylate resin oligomer, molecular weight 2700 - Between 5400, low molecular functional cure shrinkage, excellent adhesion and flexibility, exhibiting excellent macroscopic properties of the material, such as excellent adhesion and toughness , high gloss, yellowing resistance, weather resistance and excellent chemical resistance, since the main functional group-containing acrylic double bonds, radiation curable or chemically cross-linked products with light color and transparent, high adhesion scratch resistant, non-yellowing high-gloss ; wide range of applications, can be used alone as a binder for UV glue, UV curing coatings and printing inks and other products, but also systems and other acrylic, epoxy, polyurethane, nitro and other materials blended material to improve the surface adhesion and toughness, bond strength and resistance to yellowing transparency have a significant effect.
