Reaxis® C3210 - Bismuth Octoate (Catalyst Grade)
Request A Sample Download The Technical Data SheetOverview
REAXIS® C3210 (Bismuth Octoate) is a commonly used specialty metal-based bismuth catalyst for polyurethanes. With a long history of usage in a wide range of formulations, REAXIS® C3210 is a good benchmark catalyst when either starting development work on new formulations or looking at using lower-toxicity alternatives to organotins. REAXIS® C3210 has a higher bismuth metal concentration compared to REAXIS® C3208 (Bismuth Neodecanoate). REAXIS® C3210 can be supplied with a wide range of non-acid diluents including mineral oils, polyols, and esters. Similar products include REAXIS® C716, REAXIS® C3208 and REAXIS® C3209. REAXIS® C3210 is present on most international regulatory lists, making it an ideal choice when developing global formulations.

Applications
Like most bismuth carboxylates, REAXIS® C3210 is commonly used in polyurethane applications. It is used in a wide range of polyurethane applications including coatings, adhesives and sealants, foams, plastics and elastomers. REAXIS® C3210 is used in applications where toxicity concerns are paramount. In addition to its use as a polyurethane catalyst, REAXIS® C3210 can be used in lubricant formulations.
Reactivity
The use of REAXIS® 3210 as a polyurethane catalyst results in good overall reactivity. A well-balanced cure is achievable, given the presence of both a low bismuth metal content and large ligand. Thus, a balanced front-end/pot-life and back-end/ final cure reactivity profile can be achieved. Reactivity, especially in regard to back-end cure, is greatly improved with the addition of added and exothermically generated heat. Typical of the bismuth carboxylate family of catalysts, REAXIS® C3210 will catalyze most polyurethanes reactions, and is somewhat similar in reactivity to tin-based catalysts; it is primarily selective toward the polyol-isocyanate and water-isocyanate reactions. REAXIS® C3210 is hydrolytically stable within typical formulation moisture levels, but this stability will break down with increasing moisture content. In general, bismuth carboxylates exhibit a lower hydrolytic stability compared to organotins.
Package & Storage
- 44 lb (20 kg) plastic pail
- 440 lb (200kg) plastic drum
REAXIS® C3210 should be stored in the original packaging at moderate temperatures and kept from freezing. The container should be closed tightly after each use to maximize shelf life. Characteristic of most Bismuth Carboxylates, the primary cause of instability would be hydrolysis.
