Product information

TIB KAT 319 is a dibutyl tin mercaptide based catalyst.

TIB KAT 319 is used as:

  • catalyst for polyurethane coatings and elastomers
  • stabilizer for PVC

TIB KAT 319 has higher hydrolytic stability than comparable organotin carboxylates.

The catalytical reactivity of TIB KAT 319 in polyurethane systems is in most cases lower than DBTL (TIB KAT 218), resulting in longer pot life and latent reaction, but fast curing times.

The use in water-based systems is possible within certain limits.
