TIB KAT 423 – Liquid dioctyltin oxide catalyst for silicone and silane systems

TIB KAT 423 is a liquid catalyst blend based on a dioctyltin oxide formulation. The product is primarily used for the curing of silicones and silane-terminated polymer systems.

TIB KAT 423 is particularly suitable for:

  • 1-component MS/STP systems
  • Curing of alkoxy-based RTV silicones

Properties & handling

Like other tin-based catalysts, TIB KAT 423 catalyzes silanol/silane condensation and acts as a polymerization and crosslinking catalyst.

However, the product is sensitive to moisture:

  • Avoid contact with moisture as much as possible
  • Hydrolysis may occur at high humidity
  • This leads to lowering flash points
  • CAS-Nr.
