Chalco Aluminum Coat ’s unique pre-treatment is used prior to the primer and topcoat paint system. The pre-treatment is an alternating current anodizing in sulphuric acid electrolyte. The process produces a clean surface with a thin aluminium oxide film. This film is an integral part of the aluminium surface and is flexible due to its porous structure. This pre-treatment prepares the surface for excellent paint adhesion and corrosion resistance of the painted products. The pre-treatment is non-toxic and does not contain any chromium or heavy metal based chemicals and, therefore, underlines Chalco Aluminum Coat’s environmental friendly profile. The front side coating used is normally high gloss. The reverse side coating is normally a clear lacquer which has been designed for use with the types of adhesive used in bonding caravan sides. In these cases care should be taken to ensure that the Chalco Aluminum Coat lacquer is compatible with the specific adhesive to be used in practice. Samples can normally be provided for these evaluations. The reverse coating is equally a protector to the front coating, reducing the risk of pressure and metal marking, and acting as a lubricant in the forming process. Stucco embossing is available on request.
