FeCl3 40% PCB Etching Grade (CAS 7705-08-0) — a dedicated product line for PCB (Printed Circuit Board) etching, imported from India. Unlike FeCl3 for wastewater treatment: ultra-low FeCl2 content (<0.10%), tightly controlled metal impurities (Cu 0.0008%, As 0.000015%), ensuring stable copper etch rates and sharp circuit traces. COA batch 08/2026 — QC checked by Phan Cam Thuy & Vo Thi Nhu Hoa. Loc Thien bulk supply, nationwide KCN delivery. Call +84 979 891 929 — quote in 15 minutes.
5 Key Points:
- FeCl3 PCB/Etching Grade — imported from India, NOT wastewater grade
- Actual concentration 41.80%, density 1.474 (COA batch 08/2026)
- FeCl2 <0.10%, Cu 0.0008% — low impurities for precise etching
- Reaction: 2FeCl₃ + Cu → 2FeCl₂ + CuCl₂ — dissolves unprotected copper, leaving designed traces
- Batch COA — QC Phan Cam Thuy & Vo Thi Nhu Hoa approved
