BR-1151M
BR-1151M is a difunctional aromatic polyether urethane methacrylate. First of its kind in a novel class of oligomers where hardness and modulus are maximized. BR-1151M offers excellent tensile properties with high temperature stability. This oligomer has a low viscosity profile and good compatibility with fillers making it excellent for use in composites. In addition, BR-1151M demonstrates chemical resistance and toughness properties found in most 2K and thermoset systems.
