Reaxis®  C2013

REAXIS® C2013 (Dioctyl Tin bis-(Acetylacetonate)) is an octyl-based organotin with a ketonate functionality.  REAXIS® C2013 is a highly reactive neat liquid butyl tin given its high tin content (23%) and related small ligand. REAXIS® C2013 is part of the tin (IV) family of organotins. Due to its ketonate-based ligand, REAXIS® C2013 has an improved hydrolytic stability compared to carboxylate functionalized organotins such as REAXIS® C218 (Dibutyl Tin Dilaurate).  Due to its octyl nature, REAXIS® C2013 tends to be slower in reactivity when compared to its butyl analogue, REAXIS® C226 (Dibutyltin Bis-Acetylacetonate). Products with similar reactivity include REAXIS® C417V (Dioctyltin Oxide + Silane Complex) and REAXIS® C417VM (Dioctyl tin Oxide + VTMO) and REAXIS® C417 (Dioctyl tin Oxide + TPOS).  REAXIS® C2013  is on limited international regulatory lists for commercial use. REAXIS® C2013 has only a limited Low Volume Exemption TSCA status and is not listed on Canada’s DSL or NDSL. REAXIS® C2013 is only sold for commercial use in the EU.

Applications

REAXIS® C2013 and its alternatives can be used as a homogeneous catalyst in a wide spectrum of silicone applications including adhesives, sealants, and coatings. Silicone-based applications include: acetoxy-, ethoxy- and oxime-based Room Temperature Vulcanizing (RTV) adhesives and sealants, polyethylene crosslinked silanes (PEX), and select silane modified polymers (SMPs).  REAXIS® C2013 is the primary catalyst used with MS Polymer® based formulations.   

 

Reactivity

Given its high tin content, liquid form, small ligand, and good compatibility with a wide range of raw materials, REAXIS® C2013 tends to be a highly reactive catalyst across a broad range of silicone formulations. In regard to silicone reactions, REAXIS® C2013, like all tin-based catalysts, will catalyze the silanol/silane condensation reaction thus acting as both a polymerization and crosslinking catalyst. In addition to reactivity, REAXIS® C2013 is more hydrolytically stable toward condensation-generated moisture.  Reactivity-wise, REAXIS® C417VM and REAXIS® C417V would be an ideal choice in similar applications.

 

Package & Storage

Packaging

  • 2400lb (1089 kg) IBC
  • 440 lb (200 kg) steel drum

Storage

REAXIS® C2013 should be stored in the original packaging.  The container should be closed tightly after each use to maximize shelf life. Characteristic of most Sn (IV) organotins, the primary cause of instability would be hydrolysis. Hydrolysis results in the formation of tin oxide insolubles leading to deactivation of REAXIS® C2013.
