Paper varnishes play a crucial role in enhancing the aesthetics and functionality of paper products. They offer protection against scratches, moisture, and wear, while also improving printability and visual appeal. In recent years, UV-curable (UUV) oligomers, particularly epoxy acrylate oligomers, have emerged as a promising alternative to traditional paper varnishes.In this article, we will talk about how Epoxy Acrylate Oligomer from Solvacoat, RAD 532F, can improve UV OPV formulation.
What is Epoxy Acrylate Oligomers
Epoxy acrylate oligomers are a type of reactive resin, combining the beneficial properties of both epoxy and acrylate chemistry. These oligomers are known for their excellent adhesion, high reactivity, and superior mechanical properties. They are widely used in UV-curable coatings, inks, and adhesives.
Solvacoat RAD 532F is an advanced UV oligomer product specifically designed for use in UV OPV formulations. It is a versatile epoxy acrylate oligomer that performs exceptionally well under both UV mercury lamps and UV LED lamps without requiring a change in the photo initiator type. Because its flexibility can make it a preferred choice for formulators who need a reliable and effecient solution for paper varnish applications.
