· JVASP-44379· ZnCrO4

Zinc chromate (ZnCrO4) is an inorganic ceramic compound combining zinc and chromate ions, typically encountered as a yellow powder or pigment phase. It has been historically used as a corrosion-inhibiting pigment in primers and protective coatings, though its use has been restricted in many regions due to hexavalent chromium toxicity concerns; modern applications focus on specialized coatings in aerospace and marine environments where legacy formulations remain qualified, as well as in research contexts exploring chromate-based compounds for niche protective functions.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
