Coscat® 83

Coscat® 83 is an organobismuth compound that was specifically developed as a catalyst for two component, polyurethane systems. For soft to medium hardness systems the addition of a zinc catalyst can reduce a potential lag in final cure, yielding a stronger final cure typical of a mercury-based catalyst.
