Coscat™ 83

Coscat™ 83 is a proprietary organobismuth compound which was specifically developed as a catalyst for 2-component polyurethane systems. Coscat™ 83 is recommended as a sole or co-catalyst in urethane elastomer systems typically requiring lead, mercury or tin catalysts. Coscat™ 83 has a high selectivity toward the polyol-isocyanate reaction, thus avoiding bubble generation at low levels of moisture.
