Karstedt’s Catalyst
Karstedt’s catalyst is a platinum(0) complex of 1,3-divinyl-1,1,3,3-tetramethyldisiloxane, normally supplied as a solution containing about 2% platinum. The platinum centre is stabilised by two vinylsiloxane ligands, giving a highly active homogeneous hydrosilylation catalyst compatible with silicone systems.
• Silicone curing: addition-cure (hydrosilylation) elastomers, gels, sealants and release coatings.
• Silane and siloxane modification: hydrosilylation of allyl-functional polyethers, amines and epoxides.
• Crosslinking of organic polymers: hydrosilylation-based curing and silane grafting.
• Specialty coatings and adhesives: fast, low-temperature cure.
