coscat 8330r catalyst is a proprietary organo-metallic compound
that was specifically developed to provide a functional alternative to
the benchmark performance of mercurial catalysts in two component
polyurethane systems.
coscat 8330r catalyst is recommended as a sole or co-catalyst in
polyurethane elastomer systems typically requiring lead, mercury or
tin catalysts. specific benefits of coscat 8330r include a high
selectivity toward the polyol-isocyanate reaction, thus avoiding
bubble generation at low levels of moisture, excellent synergy with
organo-mercurial catalysts and improved humid aging performance
in urethane systems currently catalyzed with other organo-metallics
or amines.
