Pre-treatment Coated Aluminium Foil
Signi Coat’s pre-treatment coated aluminium foil is degreasing and chemical pre-treatment of aluminium foil. This pre-treatment is applied onto a line equipped with the best technology and it’s designed under the custom engineering concepts of Signi Coat technical group. Its main advantages are the total dispose of residual oils on surface from lamination process as well as magnesium, manganese, among others that could be on surface and might cause problems on anchorage of coating.
