Product Introduction
YWU2670 is a two-component polyurethane acrylic resin polymer with a molecular weight ranging from 2550 to 6200. It has a low molecular functionality, a small curing shrinkage, excellent adhesion and flexibility, and good weather resistance, acid and alkali resistance. It has a high cross-linking bonding elongation rate and exhibits excellent macroscopic properties such as excellent adhesion and elasticity, high gloss, excellent color retention, 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 is characterized by a light color and transparency, high adhesion and scratch resistance, high gloss without yellowing; it has a wide range of applications and can be used alone as the main resin for UV light-curable adhesives, metal coatings, PET films, OPP film screen printing inks, and can also be used as UV electronic sealants and other products.
Application scope and suggestions:
Plastic topcoat primer, topcoat resin, nail polish base, color-coated material as main resin, dosage 25-60%
UV adhesive resin can be mixed with other acrylic, epoxy and polyurethane. It is used for products such as metal PET and OPP films, with a dosage of 30 - 60%.
Electronics, cosmetics, furniture cabinet boards with UV spray finish and gloss treatment, dilution ratio 10 - 25%
Screen printing ink, with excellent adhesion and gloss, with a concentration of 30 - 60%
Other polymer adhesion and toughness modifiers, with a dosage of 10 - 30%
