USE: Curing catalyst used in adhesives and sealants for the automotive and other industries. (TMR) The PMN material is intended to replace dibutyltin dilaurate. Analog L-11-233 is used as a curing catalyst in formulated industrial adhesive/sealant products. Analog L-09-264 is used as a catalyst for elastomers. Analog P-85-1250 is used as a catalyst for a silicone sealant. Analog P-88-1619 is used as a catalyst for crosslinking coating resins. Analog P-88-806 is used as a catalyst for a silicone rubber glass sealant. Analog L-05-314 is used as a sealant curing catalyst in moisture curable sealing compounds. Analog L-08-366 is used as a catalyst for adhesives used for rubber gaskets and automotive parts.
