Product Introduction
YWU6901 is a polyurethane acrylate resin oligomer with a molecular weight ranging from 800 to 1500. It has a high molecular functionality and exhibits rapid ultraviolet light crosslinking and curing. It has strong adhesion and demonstrates excellent macroscopic properties, such as excellent hardness, high gloss, resistance to yellowing and chemical resistance. Due to the presence of main functional groups containing acrylate double bonds, it can be radiation-cured or chemically crosslinked. The product has a light color and transparency, high hardness and scratch resistance, high gloss, and no yellowing. It has a wide range of applications. It can be used alone as the main resin for UV light-cured coatings, inks, and adhesives, or can be mixed with other acrylic systems, epoxy, polyurethane, nitrocellulose, etc. It has a significant effect on improving the surface hardness, gloss, bonding strength, and yellowing resistance of the material.
