Etching and metal engraving
Ferric Chloride solution is used as an ETCHANT in PRINTED CIRCUIT BOARDS as well as ENGRAVING. This is because it acts as an excellent etchant for most metals like copper, aluminium, stainless steel, etc. The vast usage of Ferric Chloride solution is due to its fast reaction, high etching capacity and easy application
Circuits-Base Chemicals Pte Ltd
Circuits-Base Chemicals was founded in 1988 as a joint venture between Chin Leong Corporation and their Taiwanese partner to recycle spent Ferric Chloride etchant from the printed circuit board (PCB) industry.
Waste water treatment
Ferric Chloride acts as a very effective coagulant-flocculant which is used alone or with other chemicals. It has the ability to coagulate over a very wide pH range, making it a more useful tool in many instances as compared to other chemicals.
