Model No: B-20
MXC-B20
It is a bismuth-based carboxylate used as a co-catalyst with tertiary amines to accelerate the urethane reaction and cure. It serves as an alternative to tin-based catalysts in flexible slabstock, high-density flexible foams, spray, microcellular, and rigid foam systems.
Technical Data Sheet
Brand name: MXC-B20
General Description:
It is a bismuth-based carboxylate used as a co-catalyst with tertiary amines to accelerate the urethane reaction and cure. It serves as an alternative to tin-based catalysts in flexible slabstock, high-density flexible foams, spray, microcellular, and rigid foam systems.
