HAI's amine catalyst product line, Sigma Cat, is designed for use with our entire line of phenolic urethane cold box resins. Our Sigma Cat products utilize TEA (triethylamine), DMEA (dimethylethylamine), DMIPA (dimethylisopropylamine) and DMPA (dimethylpropylamine) in the vapor form as catalysts in this process.
The PUCB process utilizes vaporized amines as the catalyst to initiate a reaction between a phenolic resin and an isocyanate resin to form a urethane bond. HA-International offers Sigma Cat 2185 (TEA), Sigma Cat 2190 (DMIPA), Sigma Cat 2198 (DMPA), and Sigma Cat 2195(DMEA) Amines in both cylinders and drums.
