CORRGUARD™ LSA is a high-performance metalworking fluid additive consisting of primary amino alcohol chemistry with less than 0.75% secondary amine. The low secondary amine level of CORRGUARD LSA helps formulators meet increasingly stringent end-user and regulatory requirements, such as TRGS 611 in Germany. CORRGUARD LSA is 100% water soluble and provides high-efficiency neutralization, pH stability and corrosion control, and leaches less cobalt than most competitive amine chemistries used in today’s metalworking fluid formulations. It also enhances resistance to microbial degradation when used in conjunction with registered biocides. CORRGUARD LSA is available in multiple concentrations to support formulation and storage requirements, including CORRGUARD™ LSA 6000 (95% in aqueous solution), CORRGUARD™ LSA 7000 (90% in aqueous solution) and CORRGUARD™ LSA 8000 (75% in aqueous solution).
