TIB KAT 321
Product information
TIB KAT 321 is a dibutyl tin mercaptide catalyst.
TIB KAT 321 finds its uses in the following application:
- catalyst for polyurethane coatings and elastomers
- stabilizer for PVC
TIB KAT 321 has higher hydrolytical stability than comparable organotin carboxylates.
The catalytical reactivity of TIB KAT 321 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 with certain limits.
