Product introduction

    YWU25E85 is di-functional polyurethane acrylic resin monomer b oxidation modified oligomer, low molecular functionality, solidification shrink, excellent adhesion and flexibility, show the material macro excellent performance, such as excellent adhesion and toughness, high gloss and yellowing resistance, weather resistance and excellent chemical resistance, because the main functional groups containing allyl double bond, can radiation curing or chemical crosslinking, products with shallow transparent color, high adhesion scratch resistant, no yellowing highlights; Application scope wide, can separate as main resin used for UV glue, uv-curable coatings and printing ink, etc, and can and other acrylic system, epoxy, polyurethane, nitrocellulose, etc material blending, to improve the material surface adhesion and toughness, bonding strength and resistance to yellowing transparency has significant effect, on the basis of YWU2569S resin reduced viscosity, increase the crosslinking density, the curing speed and product hardness

Range of application and Suggestions
  • Plastic vacuum plating primer, surface coating resin as main body in the resin, the dosage of 15-40%

  • UV adhesive resin, used for metal, glass, plastic products, such as dosage of 10-50%

  • Electronics, cosmetics, furniture cabinet plate UV spray finishing, dosage of 10-30%

  • Screen printing ink, good adhesion and gloss, dosage of 10-30%

  • Other polymer adhesion and toughness modification agent, the dosage of 5-20%
