Chemical brighteners like UltraLyte 170 XL are used as part of pre-treatment during the anodising process, developed for use in both manual and automatic plants where a very high standard of finish is required. This market-leading product provides unrivalled brightness and a high degree of reflectivity on a wide range of aluminium alloys. UltraLyte 170 XL holds exceptional resistance to transfer etching — traditionally a problem on automatic anodising lines that use an on-line brightener.
