POLYCAT® SA 2 LE is a low-emissive, delayed-action tertiary amine based on DBU. It effectively enhances the urethane reaction when heat is applied, making it suitable for microcellular, integral skin, coating, adhesive, sealant, and elastomer applications. This product is especially recommended for use with low-activity aliphatic isocyanates.
