TWEHA Blacken is a specially developed black coating for aluminum supporting profiles used in ventilated and rainscreen façade constructions.

With open-jointed façade systems, the natural bright or shiny appearance of mill-finished aluminum profiles can remain visible between the cladding panels and interfere with the desired architectural appearance. Black anodized aluminum provides a solution but can add considerable cost. TWEHA Blacken offers a practical alternative by creating a uniform black surface on the visible parts of the aluminum supporting structure.

Unlike conventional decorative paint, TWEHA Blacken has been developed specifically for this application. The coating must not only adhere durably to aluminum but may also form part of the bonding surface onto which the TWEHA adhesive system is subsequently applied. This makes adhesion performance an essential characteristic of the product.
