Diphenyl Bismuth Chromate (CAS 102-06-7), chemically identified as Diphenylguanidine Chromate, is a specialized thermal latent catalyst and yellow powdered pigment primarily utilized in the formulation of high-performance epoxy resins and industrial primers. Despite the industry trade name containing "Bismuth," this compound is chemically a complex of 1,3-Diphenylguanidine and chromic acid, functioning as a dual-action additive: it acts as a heat-activated accelerator for epoxy-dicyandiamide curing systems and provides exceptional passivation against corrosion on metal substrates. This Bis(1,3-diphenylguanidinium) chromate complex releases active amine species only upon reaching dissociation temperatures (typically >130°C), offering long shelf-life stability for one-component (1K) adhesives and powder coatings. To support industrial-scale requirements, we provide bulk supply with competitive factory pricing and ensure rigorous quality control through customized specifications alongside standard technical documentation, including MSDS, TDS, COA.

FAQ - Technical & Supply Chain
-
Q:
Why is this product referred to as "Diphenyl Bismuth Chromate" if it contains no Bismuth?
A: This is a common historical trade name in the Asian chemical market; the product is chemically Diphenylguanidine Chromate, and the "Bi" likely refers to the "Bis" (two) phenyl groups or a phonetic mistranslation, rather than the metal Bismuth. -
Q:
What is the advantage of using this catalyst (CAS 102-06-7 derivative) in epoxy systems?
A: It functions as a "latent" catalyst, meaning it remains inert at room temperature to maximize pot life, but rapidly accelerates the curing reaction when heated, while simultaneously providing corrosion protection to the bonded metal interface.
