Silver bromide

Silver bromide (CAS 7785-23-1, EC 232-076-8), also known as AgBr or argentous bromide, is an inorganic silver salt formed from silver and bromine. It carries no E-code designation and is classified under salts and minerals. It is registered under REACH and handled in accordance with applicable EU chemical regulations.

In electronics manufacturing, silver bromide serves as a functional component in photosensitive coatings and conductive surface treatments, where exposure to light triggers a reduction reaction that converts Ag+ ions to metallic silver, enabling precise pattern formation. It is also applied in surface modification processes to alter substrate wetting behaviour and adhesion characteristics at the interface level.

Silver bromide is supplied as a pale yellow powder in technical and high-purity grades suited to electronics and specialty formulation applications. It falls under HS code 2843290000 and is subject to REACH compliance requirements. Packaging formats are available on request and aligned with standard B2B procurement volumes.
