Lupragen® N101 (DMEOA aka DMEA, Dimethylethanolamine) is a liquid tertiary ethanol amine.
Lupragen® N101 inherits both, a tertiary amine and hydroxyl group.
As a tertiary amine Lupragen® N101 accelerates the gel reaction during the formation of polyurethanes (PU).
The free hydroxyl group binds chemically into the PU matrix. Lupragen® N101 is therefore classified as a “reactive” catalyst with low residual odor.
As a gelling catalyst Lupragen® N101 is usually mixed with a blowing catalyst like Lupragen® N205 (BDMAEE).
