What is BS EN 4868 - Hexavalent chromium-free anodic electrodeposition about ?
BS EN 4868 specifies the requirements for hexavalent chromium-free anodic electrodeposition of organic coatings on aluminium and aluminium alloys for corrosion protection of parts.
BS EN 4868 establishes requirements for a waterborne, hexavalent chromium-free corrosion inhibiting, chemical and solvent resistant, anodic electrodeposition of organic coating capable of curing at 110° to 120° C.
Who is BS EN 4868 - Hexavalent chromium-free anodic electrodeposition for ?
BS EN 4868 on hexavalent chromium-free anodic electrodeposition is useful for:
- Primer manufacturers
- Aluminium and aluminium alloy manufacturers
- Quality control personnel for primers
- Design engineers for military aircrafts
- Quality control personnel for military aircrafts
- Aircraft manufacturers
Why should you use BS EN 4868 - Hexavalent chromium-free anodic electrodeposition ?
Organic coatings are a complex mixture of polymers, fluid carriers, pigments, corrosion inhibitors, and additives. As far as aluminium and aluminium alloys are concerned, organic coatings are commonly used to protect engineering structures and manufactured products from corrosion.
Anodic electrodeposition is an industrial coating method in which negatively charged organic coating particles in the aqueous solution migrate (electrophoresis) toward the anode of a direct-current electrical circuit passing through the solution, so that electrolysis of water creates a localized pH gradient, precipitating a uniform layer of coating on the anode.
Hence, BS EN 4868 gives you guidelines on design, quality, and manufacturing requirements for hexavalent chromium-free anodic electrodeposition of organic coatings.
As a manufacturer, you can use guidelines given in BS EN 4868 on coatings with uniform control, complete coverage of recessed areas, minimal surface defects and high transfer efficiency.
By adopting BS EN 4868, you can manufacture the best quality primer that is used for protecting against corrosion and masking before anodizing.
