BIS-PROPARGYL-SUCCINATE (BPS)
BPS
BPS acts as a curing agent analog to isocyanate in classical polyurethane systems. It can be varied in its content to influence on the mechanical properties of the cross-linked binders as measured by tensile tests. The mechanical properties can be adjusted in a wide range by varying the amount of BPS.
