FAQ
Bronze powders are susceptible to oxidation in humid or alkaline conditions, turning the gold to green. Use with acid-functional binders, add chelating stabilisers (benzotriazole type), minimise water content, and use airtight packaging. Lacquer-coated grades are also available for better oxidation resistance.
