ETCHAL

Aluminium Etch Additive AE2 is a chlorate free additive to provide a long-term stable etch with reduced sludge formation. The etch can be run as a continuous basis without dumping if properly maintained. The etch gives excellent results on extrusions removing die lines and extrusion blemishes.

Etch Additive LG is a highly concentrated additive with a correct blend of sequestering agents that significantly reduce 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.

Additive AA has been developed to enable hard anodised coatings to be produced at standard anodising temperatures. Additive AA increases the operating ranges of temperature and current density to achieve more consistent results.
