CORRGUARD™ SELECT LSA is a new-to-world, readily biodegradable multifunctional additive exclusively manufactured by Advancion to provide superior performance with an excellent safety profile for metalworking fluids. CORRGUARD SELECT LSA consists of primary amino alcohol chemistry with less than 0.75% secondary amine, and is specifically designed to help formulators meet regulatory requirements, such as TRGS 611 in Germany.
CORRGUARD SELECT LSA offers well-balanced performance that provides highly effective multi-metal compatibility and reduces cast iron corrosion, aluminum staining, and cobalt leaching. CORRGUARD SELECT LSA is a highly efficient neutralizer with a high pKa, provides excellent pH stability and enhances microbial degradation resistance when used with registered biocides. CORRGUARD SELECT LSA is 100% water soluble and has excellent hard-water stability, low foaming, and offers improved solubility in synthetic and renewable base oils.
CORRGUARD SELECT LSA is available in several concentrations to support formulation and storage requirements, including CORRGUARD™ SELECT LSA 6000 (5% water), CORRGUARD™ SELECT LSA 7000 (11% water) and CORRGUARDTM SELECT LSA 8000 (25% water).
