Reaxis®  C129

REAXIS® C129, Stannous Octoate,  is a metal-based homogenous stannous tin catalyst that is used in a number of application chemistries, including:

  • Esterifications
  • Polyurethanes
  • Silicone condensation reactions
  • Lactone polymerization to form biodegradable polymers

Stannous Octoate can be utilized neat or as a mixture of various diluents. When considering catalysts with similar reactivities to REAXIS® C125 (Stannous Neodecanoate), Stannous Octoate is a good candidate given the similar metal concentrations and ligand make-up.

Stannous Octoate is used in a wide range of end-use applications as a catalyst, including, coatings adhesives/sealants, elastomers and foams. Stannous Octoate can be used as an additive in lubricants to enhance heat stability and minimize substrate corrosion.
