AA-200 (Aluminum Anodizing Additive)

METALAST AA-200 is a proprietary aluminum anodizing, specialty chemical additive. AA-200 is a combination of organic monomers specially formulated to prevent the processed part from burning during the aluminum anodizing stage. Typically a nickel acetate seal would follow this stage, producing a high quality, uniform oxide and improved throughput.  AA-200 is another all product RoHS compliant specialty chemical that meets OSHA regulations and is available to the metal finishing industry. As the patent holder and only chemical supplier of the AA-200, METALAST is pleased to offer the next generation of aluminum anodizing additives to the metal finishing industry. 

METALAST TCP-HF

METALAST TCP-HF and the soon to be released METALAST TCP-HF/EPA (extended protection additive) are environmentally safe and superior trivalent chromate chemical alternative to hexavalent chromates. These “green” trivalent chromate chemicals, along with other aluminum anodizing products, are the trademarked products of METALAST International, LLC and can only be purchased through METALAST or its authorized chemical supplier, manufacturer and distributor, Chemetall Oakite.

METALAST TCP-HF and METALAST TCP-HF/EPA are RoHS compliant products and meet the mil-c-5541 spec, OSHA regulations and the hex European Union ELV directive.  METALAST TCP-HF and METALAST TCP-HF/EPA are both QPL approved (May 2006 and October 2007 respectively) and are the only viable and superior performing trivalent chromate and RoHS compliant  hex substitutes available to the aluminum anodizing and metal finishing industry.  These trivalent chromate chemicals are environmentally safe and superior performing alternatives to hexavalent chromates that are now being banned globally by regulations such as the RoHS, WEEE, ELV and the OSHA regulation PEL.  Both trivalent chromate products are user friendly and can be applied at room temperature with no odor and a pH close to neutral.
