Product introduction

 YWU2901 is di-functional polyurethane acrylic oligomer, the molecular weight between 2500-3500, molecular weight, high cohesive energy, stick relay is strong, show the material macro excellent performance, such as excellent adhesion and plated, high gloss and yellowing resistance and chemical resistance, because the main functional groups containing allyl base double bond, can radiation curing or chemical crosslinking, products with shallow transparent color, high adhesion, resistance to scratch, no yellowing highlights; Application scope wide, can separate as main resin used for UV light curing coatings, inks and adhesives and other products, and can and other acrylic system, epoxy, polyurethane, nitrocellulose, etc material blending, to improve the materials on the adhesion and plating, bonding strength and resistance to yellowing transparency has significant effect
