vegaform evolution benefit performance of our PVD coated finishes in applications requiring hollow forming and deep pressing. vegaform evolution is a range of medium to soft temper, aluminium based, reflector materials produced from pre-anodized aluminium coated with special high reflectance PVD layers designed to provide high light output even after deep drawing operations. The high reflectance coatings are applied to coil and flat sheet products. vegaform evolution can be deformed using specially softned adapted pressing techniques and the coating technology employed allows the reflector...

Environmental tests Temperature resistance Panels of vegaform evolution VFE95100 have been held at a temperature of 250°C for 7 days and no reduction in reflectance values or change in visual appearance was observed. In the case of hard rolled products there would be, of course, a softening of the aluminium after this treating but as vegaform evolution is already produced in a softened condition it is not so affected. Humidity tests In humidity tests, at 100% humidity at 38°C (ISO 6270-1), the evolution products show the same good resistance to deterioration as anodized aluminium. This has...
