BR-3741AJ is an aliphatic 1.3 acrylate functional polyether urethane. The extremely elongating nature of BR-3741AJ makes it an excellent candidate for consideration in UV light-curable PSAs as a reactive tackifier. It is also used as a co-oligomer for adhesion promotion in coatings. Films formulated with BR-3741AJ are highly flexible, elastomeric, and tacky. This oligomer is an excellent adhesion promoter, and compared to other reactive tackifiers it results in relatively tougher films. It is a perfect choice for optically clear UV pressure-sensitive adhesives (PSAs).
Bomar specializes in the synthesis, formulation, and manufacture of advanced performance oligomers and materials for energy (UV/EB), light, and other free-radical cure applications worldwide.
