History
During the 1960's Sandoz (Basle) developed a range of dyestuffs that were sufficiently light resistant to be used on the exterior of buildings. In the 1980's these colours were supplemented by the Sandalor range, using a bronze underlay on these bright colours.
LHT Anodisers were granted an Interoxyd license in 1983 to process the Sandalor range and are still the only licensee in the UK. A spray dye plant was installed, the only one operational on architectural finishes in Europe.
Benefits
In addition to the general anodising benefits (see "anodising") Sandalor finishes produced by the Anolok method using Cobalt are more durable in respect to colour fastness and gloss retention than the latest polyester powder coat resins.
