Dioctyltin – silane complex is an organotin compound where dioctyltin is coordinated with silane groups, typically alkoxysilanes like vinyltrimethoxysilane (VTMO).
Dioctyltin – silane complex is engineered to catalyze hydrolysis and condensation reactions in moisture-curing systems, particularly in silyl-terminated polymers (MS polymers) and alkoxy-based RTV silicone systems.

Its unique structure allows Dioctyltin – silane complex to function effectively as both a catalyst and a stabilizer, enhancing the performance of various polymer-based formulations.
Dioctyltin – silane complex (Dioctyltin Oxide + Silane), also known as DOTO + Silane or Dioctyl tin oxide + silane is a liquid version of dioctyltin oxide (DOTO) containing tetrapropyl ortho silane (TPOS) and is commonly used as a catalyst for silicone chemistries.

As an octyltin-based catalyst, Dioctyltin – silane complex is a moderately active catalyst that is ideal for use in adhesive and sealant formulations utilizing TPOS as an additive for increasing hydrolytic stability.
Other silane grades include REAXIS C248T (DBTO+ tetraethylortho silane/TEOS) and REAXIS C417VM/V (DOTO + VTMO).

Other liquid grades of Dioctyltin Oxide are available upon request.
Dioctyltin – silane complex is present on a wide range of international inventory lists, making it an ideal choice for international formula development.
