【Application】
2,2'-Dimorpholinodiethyl ether (DMDEE) is a strong foaming catalyst for polyurethane systems. The steric hindrance of its amino groups ensures extended storage stability for NCO‑containing formulations. Primarily used in one‑component rigid polyurethane foams, and also suitable for polyether/polyester flexible foams, semi‑rigid foams, and CASE applications (coatings, adhesives, sealants, elastomers).

【Product Specification】
Purity (DMDEE) ≥ 99.0% by GC.
