WebSep 15, 2024 · The bismuth compounds have been characterized at different ratios of bismuth to carboxylate as solutions of the free acids. Their structures are most consistent with a Bi4 (RCO 2) 12 motif where the Bi ions are arranged in a flattened tetrahedron with Bi – Bi distances of about 4.3 Å. WebBiCAT® 8106 is our low free acid bismuth carboxylate at 20 wt% bismuth. This material has been successfully used in one- and two-component systems for ambient or heat cure systems. Additionally, BiCAT® 8106 has been successfully used in HFO-based polyurethane spray foam systems.
