Polycat® 140

Polycat® 140 by Evonik is a low-emissive amine catalyst for low density, water blown, open-cell spray polyurethane foam (SPF). This is a reactive catalyst and more selective for the water-isocyanate blowing reaction. It can replace standard blowing catalysts based on BDMAEE such as Dabco® BL-11 and Dabco® BL-19 catalysts. It can be used in combination with Polycat® 141 or Polycat® 142 catalysts to effectively replace emissive catalyst packages based on BDMAEE [bis(dimethylaminoethyl)ether]. Due to its chemical structure, it can react into the foam, significantly reducing off-gassing over time and amine-related odor when used in combination with Polycat® 31, Polycat® 141 or Polycat® 142 catalysts. A modest increase in use level is typically required when using this grade compared to BDMAEE based catalysts. Polycat® 140 can be used in water blown, low-density spray polyurethane foam. It has a shelf life of 24 months.
