Used as a catalyst in polyurethane foam production, particularly in flexible slabstock foams. It promotes the blowing reaction, helping to control foam rise and cell structure. Also employed in rigid foams for insulation, where it contributes to achieving desired density and thermal properties. Its high activity makes it effective in low concentrations and at low temperatures. Commonly used in combination with other catalysts to balance reactivity and processing time. Found in adhesives, sealants, and coatings systems where controlled cure profiles are needed.
