Ammonium Persulfate Supplier India | APS Powder for Etching

Ammonium persulfate ((NH₄)₂S₂O₈) from Drashti Chemicals initiates polymerisation, etches printed circuit boards, cleans metal surfaces, and supports textile desizing across Gujarat. Strong oxidiser — store away from reducers, organics, and moisture. COA confirms assay and active oxygen — degraded persulfate fails PCB etch rate and wastes bath chemistry.

Industrial grade (≥98%) for PCB and metal treatment; confirm moisture content on COA — damp persulfate clumps and decomposes. Persulfate generates persulfuric acid in water — use HDPE or PP equipment. Shelf life 12 months in sealed container below 30 °C. Drashti rotates stock to ensure fresh material for etch-line consistency.

PCB etching: 100–200 g/L with copper sulphate accelerator at 40–50 °C; replenish based on etch rate (minutes per mil). Metal cleaning: 50–100 g/L dip for 5–15 minutes. Textile desizing: 2–5 g/L with heat. Dose as solid into agitated bath — predissolve in separate tank for metering. Exhaust ventilation mandatory — ozone and acid mist form during decomposition.

Packaging: 25 kg HDPE bags. MOQ one bag; bulk quote on request for PCB clusters in Gandhinagar and Vadodara. MSDS and COA per lot. Store dry, cool, separate from combustibles. GST 24AGLPC6288M1ZX. Drashti Vadodara — hazmat documentation for interstate dispatch.

Persulfate vs. hydrogen peroxide for etching: persulfate is slower, more controllable, standard for PCB; peroxide is faster but harder to stabilise. Persulfate vs. ferric chloride for PCB: ferric chloride etches copper directly; persulfate needs accelerator bath. For polymerisation initiation, persulfate vs. AIBN: persulfate is water-soluble; AIBN for organic solvent systems.
