Coloured blind rivets, visuallyappealing with additionnal corrosion protection. GESIPA blind rivets are also available in colour to match the application. To guarantee the best possible durability the hollow rivets are painted using a two-component epoxy resin paint in a stow enamelling process. In addition to the visual benefits, the painted blind rivet also has added protection against corrosion. Aluminium blind rivets are best suited for this procedure. In the longterm they achieve the desired visual effect when joining coloured parts. GESIPA blind rivets are available in the standard RAL colours. On request, steel blind rivets are also available in RAL colours or even special colours. Another method for colouring blind rivets and for protecting them against corrosion is to anodize them. GESIPA blind rivets are anodized in a direct current sulphuric acid process. The term Eloxal is used to describe the electrolytic oxidation of aluminium. Eloxal itself is actually colourless. Applying a second coat using metal salts creates the desired light-fast colour. The Eloxal method is more complex but is the most durable process for coloured blind rivets. The range of coloured blind rivets includes 15 RAL colours in ten different dimensions each. The blind rivets are pro- duced in a wet varnish drum process. The colours are similar to the RAL colours.
