Whether you need a pressure sensitive adhesive with high peel strength or a less aggressive PSA that can be repositioned, UV curable adhesives can work for you. Careful selection of formulation components, film thickness and curing conditions will deliver just the right balance for your application.
As illustrated by the data below, a wide range of adhesive properties can be achieved depending on the components used in your formulation.
