Product Description

Product Description

Product Name:HN-5562Adhesive Resin for Solar PhotovoltaicBacksheet Coatings

1. Brief Introduction:HN-5562 is a premium, solvent-based, one-component adhesive resin designed with a backbone structure enriched with special functional monomers. These enhance interfacial adhesion, making it ideal for high-performance solar photovoltaic backsheet coatings. This product significantly boosts adhesion between the coating and EVA, POE, and other adhesive films. Even a small addition of HN-5562 markedly improves the shakeout resistance and flexibility of the coating, ensuring superior performance and longevity.
