Overview
HGDT-9 is a tin(II) carboxylate catalyst widely used in polyurethane systems for its high catalytic activity in gelation and curing reactions. It offers a reliable alternative to traditional tin catalysts in flexible and rigid foam, coatings, adhesives, and sealant applications.
Applications
- Polyurethane foam catalysis (gelation-selective)
- Coatings, adhesives, sealants, and elastomers (CASE) formulations
- Silicone RTV curing systems
- General esterification and condensation catalysis
Key Benefits
- Strong gelation activity, useful for balancing rise/cure profiles in foam systems
- Good solubility and compatibility across common polyol and resin systems
- Effective at low use levels
