Surface Treatment Chemicals

Am I alone in thinking that most 'speciality' chemicals for the pre-treatment of metals prior to plating are just commodity acids and alkali's with a fancy brand name ?

For example a 25 litre container of phosphoric acid 81% should cost no more than £75.00, less for a larger volume and even less for an 18% solution.

The same applies for Sulphuric, Hydrochloric, Caustic Soda and Sodium Chlorate etc..

Abbatoir effluent treatment, DAF and the rest! We often get a call to cover a staff shortfall, mainly due to long term sick leave etc and we are more than happy to oblige, it pays the bills of course!
