REAXIS® C129 (Stannous Octoate) is an inorganic tin carboxylate that consists of one of the highest metal contents for a liquid-based inorganic tin carboxylate, often used for polylactide polymerization. Chemically, REAXIS® C129 is commonly referred to as either stannous octoate or 2-ethylhexanaote. REAXIS® C129 is an ideal candidate when looking…
C218 – Dibutyltin Dilaurate
REAXIS® C218 (Dibutyltin Dilaurate), commonly abbreviated to DBTDL, is one the most commonly used specialty metal-based catalysts for polyurethanes and silicone condensation reactions. With a long history of usage in a wide range of formulations, REAXIS® C218 is a good benchmark catalyst when starting development work on new formulations. Typically…
C220 – Monobutyltin Tris-(2-ethylhexanoate)
REAXIS® C220 (Monobutyltin Tris-(2-Ethylhexanoate)) is a liquid organotin homogenous catalyst that is used primarily as an esterification catalyst. Alternatively, but less common, REAXIS® C220 can be used as a polyurethane catalyst. REAXIS® C220 is a monobutyltin -based organotin that is lower in toxicity compared to dibutyl-based organotins. Of the commonly…
C227
REAXIS® C227 (Dibutyltin bis-(1-thioglycerol)), also known as Dibutyl bis-(2,3-Dihydroxypropyl Mercaptan), is butyl-based dialkyl organotin with added functionality. REAXIS® C227 has the characteristic reactivity of a Sn (IV) organotin catalyst with improved upfront delay and improved hydrolytic stability due to the presence of a ligand with thiol functionality. Used primarily in…
