Product Introduction
YWU2569S is a two-component polyurethane acrylic resin polymer with a molecular weight ranging from 2700 to 5400. It has a low molecular functionality, excellent adhesion and flexibility, and exhibits excellent macroscopic properties of the material, such as excellent adhesion and toughness, high gloss, excellent color resistance, weather resistance and chemical resistance. Due to the presence of primary functional groups containing allyl double bonds, it can be radiation-cured or chemically cross-linked. The product has a light color and transparency, high adhesion and scratch resistance, high gloss without yellowing; it has a wide range of applications. It can be used alone as the main resin for UV adhesives, UV-curable coatings and screen printing inks and other products, and can also be mixed with other acrylic systems, epoxy, polyurethane, nitrocellulose and other materials. It has a significant effect on improving the surface adhesion and toughness, bonding strength and yellowing resistance and transparency of the material.
Application scope and suggestions:
Plastic vacuum primer, with medium coat resin as the main resin, with a proportion of 15-40%
UV adhesive resin, used for metal, glass, plastic and other products, with a dosage of 10 - 50%
Electronics, cosmetics, furniture cabinet boards with UV spray finish and gloss treatment, dilution ratio 10 - 30%
Screen printing ink, with excellent adhesion and gloss, with a concentration of 10 - 30%
Other polymer adhesion and toughness modifiers, with a dosage of 5 - 20%
