SEQENS launches multifunctional additive for water-based MWF

Amines are widely used in water-based metalworking fluid (MWF) concentrates, to neutralize  acid-functional components and maintain alkaline pH once diluted by the end user. Today, it  is a major challenge for formulators to find effective amines considering new regulations in a  globally changing environment. 

Commonly used amines, such as monoethanolamine (MEA), triethanolamine (TEA),  monoisopropanolamine (MIPA) and 2-amino-2-methyl-1-propanol (AMP) have different  advantages in terms of neutralization and buffering efficiencies. Because of differences in  amine costs, neutralization and buffering efficiencies, metalworking fluids are often formulated with  multiple products.  

Amines also often impact other very important fluid characteristics such as corrosion control,  foam development, cobalt leaching and microbiological resistance.  

The choice of multifunctional amines is a key factor as the metalworking industry is changing. 

SEQENS, a world leader in pharmaceutical solutions and specialty ingredients based in Ecully, France, has introduced a new multifunctional additive for water-based metalworking fluids called LOSMA CARB M. 

According to SEQENS, LOSMA CARB M can help formulators in finding an answer to their need for longer lasting and higher performing metalworking fluids, as stricter regulations and safety concerns have limited the choice of available additives. LOSMA CARB M is an additive for water-based metalworking fluids and auxiliary products  formulations with alkaline buffering capacity. It is a colorless, water soluble, low volatile liquid with a mild odor.  

LOSMA CARB M is an alternative to primary amines that is used in water miscible systems to  boost pH and improve additional buffer capacity. It also provides good protection for ferrous  metals corrosion and has a safer labelling than conventional amines.
