REAXIS^® C417V and its alternatives can be used as a homogeneous catalyst in a wide spectrum of silicone applications including adhesives, sealants, coatings and elastomers. 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) such as those based MS Polymer™ and SPUR+™ polymer platforms. REAXIS^® C417V is ideal for use in adhesive and sealant formulations utilizing VTMO as an additive for increasing hydrolytic stability. REAXIS^® C417V is an ideal replacement for the acetyl acetonate-based catalysts, REAXIS^® C226 and REAXIS^® C2013. 

Given its high tin content, liquid form, and good compatibility with a wide range of raw materials, REAXIS^® C417V tends to be a moderately- reactive catalyst across a broad range of silicone formulations. In regard to silicone reactions, REAXIS^® C417V, like all tin-based catalysts, will catalyze the silanol/silane condensation reaction, acting as both a polymerization and crosslinking catalyst. REAXIS^® C417V is hydrolytically stable within typical formulation moisture levels, but this stability tends to break down with increasing moisture content. This characteristic hydrolytic stability is enhanced given REAXIS^® C417V’s octyl nature and is typically an improvement compared to the use of similar butyl-based organotins, like REAXIS^® C248T and REAXIS^® C248VM,  and methyl-based organotin catalysts. It has been determined that the silane acts as a non-reactive diluent and thus does not affect catalyst efficiency. 

Packaging

• 44 lb (20 kg) plastic pail
• 440 lb (200 kg) steel drum
• 2500 lb (1,134 kg) IBC

Storage

REAXIS^® C417V should be stored in the original packaging at moderate temperatures. The container should be closed tightly after each use to maximize shelf life. Given the presence of a silane, hydrolytic instability could occur resulting in reduced catalytic performance. Due to the presence of VTMO, REAXIS^® C417V is classified as a flammable compound.
