Bisomer PPA6 offers a less traditional route to the production of UV curable urethane acrylate oligomers. As an alternative to HEA and HPA, it is non-toxic, easy to handle and listed as a polymer in the EINECS classification. Bisomer PPA6 is also an excellent, low shrinkage reactive diluent for UV systems based on urethane acrylates and vinyl esters (epoxy acrylates).
