Etchal Plus is a highly concentrated mixture of caustic soda with a correct blend of sequestering agents that significantly reduces the risk of sludge formation in the etch tank. If properly maintained, the etch tank can be run as a never dump system. Irritating caustic fumes are reduced dramatically with the fume suppressing ability of the Etch Additive LG. It is suitable to provide an attractive, matte and reproducible finish on aluminium parts.
