Product Introduction
YWU0108 is a two-component polyurethane acrylic resin polymer with low molecular functionality. It has a small curing shrinkage, excellent adhesion and flexibility, good water resistance, acid and alkali resistance, fast cross-linking curing speed, and exhibits excellent macroscopic properties such as excellent adhesion, especially for difficult-to-adhere substrates such as glass, metal, and PP substrates. It also has high gloss, resistance to yellowing, water resistance, and chemical resistance. Due to the presence of acrylic double bonds as the main functional groups, 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 a main resin for UV curing coatings on glass, metal, PP, PET, BMC and other substrates, or can be used as UV adhesives, nail polish, and screen printing inks, etc.
Application scope and recommendations:
For plastics, metals, glass and nail polish resin, as the main resin in coatings, with a dosage of 30-60%
UV adhesive resin can be mixed with other acrylic, epoxy and polyurethane. It is used for products such as metals, glass and plastics, with a dosage range of 10 - 50%.
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 20 - 60%
Other polymer adhesion and toughness modifiers, with a dosage of 5 - 20%
