Products in Monomers & Intermediates: Oligomer

BR-990S2 is a dual-functional urethane acrylate with isocyanate functional groups. While products formulated with BR-990S2 can be cured with a UV light source, a free isocyanate can also react with ambient moisture to complete the curing process. This UV+moisture curing process will benefit applications where shadow areas are present. BR—990S2 can also be used as a component in a 2K UV+Heat curable product, the other component being a polyol, glycol, or other compound with OH functional groups. A diol, or compound with two OH groups, will exhibit the best properties because it enables chain growth rather than chain termination. BR-990S2 exhibits good flexibility and develops good tensile strength when cured using both UV light and moisture. More flexible products can also be formulated with BR-990S2, different polyols, and UV+heat curing processes.
