ANGUS Unveils New Multifunctional Primary Amine to Metalworking Industry
Cleveland, Ohio - May 18, 2008 ANGUS Chemical Company (ANGUS), a wholly-owned subsidiary of The Dow Chemical Company (Dow), and the leading manufacturer of nitroalkane-based chemistry, introduces CORRGUARD™ EXT Amine Alcohol at the STLE Annual Meeting in Cleveland, Ohio. CORRGUARD EXT is a new, patent-pending primary amine alcohol developed specifically for use in long-life metalworking fluids. “The CORRGUARD EXT molecule developed at the ANGUS research and development facility in Buffalo Grove, Illinois was specifically made to meet customers’ needs,” said Nanette Hermsen, global marketing manager, ANGUS. “As the metalworking fluid industry matures, ANGUS continues to identify opportunities for innovation and strives to deliver products and solutions that directly respond to our customers’ challenges.” CORRGUARD EXT offers exceptional benefits and provides superior performance versus other primary amine alcohols in all types of water-dilutable metalworking fluids. It can be used in combination with other amines or as the only amine in formulations since it has an intermediate equivalent weight. Further, CORRGUARD EXT enhances the performance of many biocides and has shown particularly good synergy with benzisothiazolinone (BIT), a biocide that does not contain or release formaldehyde. This combination helps control bacteria and fungi for longer periods, improves ferrous metal corrosion control and pH stability, and provides longer overall fluid life maintenance. “The synergistic advantages of CORRGUARD EXT combined with BIT against both bacteria and fungi are dramatic,” said Hermsen. “The combination of CORRGUARD EXT and BIT has been shown successful in fighting bacteria and fungi commonly found in metalworking fluids, including Pseudomonas, a strain that is difficult to control with BIT in many metalworking formulations.” Key benefits of CORRGUARD EXT include ease of formulation, greater neutralization and improved pH development efficiency. Additionally, CORRGUARD EXT offers the advantage of forming emulsifiable salts with long-chain fatty acids such as tall oil. In contrast, some higher equivalent weight amines are difficult to emulsify and require larger levels of surfactants to stabilize concentrates and dilutions. This is especially prevalent in geographical areas that want to minimize the use level of ethoxylated surfactants, such as nonylphenol derivatives, due to toxicological concerns and bioaccumulation effects. About ANGUS ANGUS Chemical Company continues to develop and deliver distinct nitroalkane-based chemistries for customers in applications as diverse as paints and coatings, personal care and cosmetics, metalworking fluids, water treatment, biological buffers, solvents and thinners, wood adhesives, pharmaceutical and agricultural intermediates. Aligned as a market-focused, problem-solving specialty chemicals business, ANGUS is a wholly owned subsidiary of The Dow Chemical Company.
