Expanding the Product Range for UV Curable Pressure Sensitive Adhesives

The use of UV-curable pressure sensitive adhesives (PSAs) allows for improved manufacturing without the need for solvents. The range of products using this green technology is expanding and is comprised of unique mixtures of structurally different building blocks such as polyols, isocyanates and acrylic polymers. These new polymers can be formulated with various additives such as acrylic monomers and oligomers, plasticizers, tackifiers and crosslinkers, to provide a solvent-free and radiation curable product that offers tack, adhesion and high temperature cohesive strength when applied to both high and low surface energy substrates. They allow for improved manufacturing parameters including high deposition in a single pass and coating at elevated speeds. The invented technologies target primarily the high performance tape market.
