recommendations for use.
dabco mb20 catalyst can be used in the manufacture of rigid foams, microcellular elastomers and high density flexible polyurethane foams as an alternative to traditional metal catalysts based on dibutyltin, lead or mercury.dabco mb20 catalyst improves on the problem of long cure times associated with amine-only catalysts, and in synergistic combinations with other polyurethane amine catalysts, additional activity is gained, resulting in fast curing with excellent foam performance, and does not contain dibutyltin.
other industries where dabco mb20 catalyst can be used include high-density structural rigid foams, rigid sprayed rigid foams, rigid foam sandwich panels, sandwich boards, reaction injection molding (rim) and integral skin foams.
