Product Introduction
YWU2704 is a two-component acrylate esterified polyester resin oligomer with a molecular weight ranging from 2000 to 4000. It has a low molecular functionality, excellent adhesion and flexibility, and contains a tackifying group. It has strong adhesion, good impact resistance, and exhibits excellent macroscopic properties such as excellent adhesion and toughness, high gloss, excellent resistance to yellowing, water resistance, and chemical resistance. Due to the presence of main functional groups containing acrylate 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-curable coatings, UV adhesives, PET, PMMA, PP film inks, and glass adhesives, and can also be mixed with other acrylic systems, epoxy, polyurethane, nitrocellulose, etc. It has a significant effect on improving the surface adhesion and toughness, bonding strength, and chemical resistance of the material.
