Product Introduction
YWU2756 is a two-component aliphatic polyurethane acrylic resin oligomer with low molecular functionality. It has a small curing shrinkage, excellent adhesion and toughness. It exhibits excellent macroscopic properties such as excellent adhesion and elastoplasticity, high gloss, excellent color resistance, weather resistance and chemical resistance. Due to the presence of acryl vinyl double bonds in the main functional groups, it can be radiation-cured or chemically cross-linked. The product has a light color and transparency, high adhesion, impact 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-cured vacuum coating paints and screen printing inks, etc., 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, impact resistance and color resistance of the material.
Application scope and recommendations:
Plastic vacuum primer, used as the main resin in the primer resin, with a content of 30-60%
UV bonding agent resin, used for metal, glass, plastic and other products, with a content of 20 - 50%
UV spray varnish for electronics, cosmetics, furniture and cabinet boards, with a content of 30 - 70%
Screen printing ink, with good adhesion and gloss, with a content of 20 - 30%
Other polymer adhesion and toughness modifiers, with a content of 5 - 20%
