Lupragen® N400 is a tertiary amine with a free hydroxyl group. which is mainly used as polyurethane catalyst.
Lupragen® N400 (TMAEE, 2-[[2-(dimethylamino)ethyl]methylamino]ethanol) is mainly used as polyurethane catalyst. Lupragen® N400 belongs to the group known as blowing catalysts for polyurethane foams.
Applications of Lupragen® N400 range from rigid foam (e.g. spray foam) to flexible foam (e.g. slabstock, packaging, automotive).
By its free hydroxyl group Lupragen N400 binds chemically into the polyurethane structure and hold therefore the attribute "low VOC" catalyst.
