AminCat PMDETA catalyst is very effective in pour-in place polyurethane systems (such as rigid appliance systems), which are based on MDI. At a use level of 1.5 php, AminCat PMDETA catalyst provides the necessary flow ability and cure rates required in the production environment. AminCat PMDETA catalyst is also recommended for TDI, TDI/MDI and MDI HR flexible molded foams, as well as for use in integral skin and microcellular systems. It can also be as a raw material to make quaternary ammonium salt.


Available packaging: 170 KG steel drums and 800 KG IBC’s.
Special packaging is available on request.
