MASON CS 445C is a 50% active didecyldimethyl and MASON CS 525C is a 50% active didodecyldimethyl ammonium carbonate/bicarbonate in a water/methanol solution, for use in EPA unregistered applications.
Cationic surfactants have a multitude of uses. MASON CS 445C/CS 525C are unique quaternary ammonium compounds that does not contain metal corroding halogens such as chloride or bromide. CS 445C/CS 525C are manufactured from a renewable resource alkyl amine derived from coconut oil and dimethyl carbonate, a biodegradable “green reagent.”
Use MASON CS 445C/CS 525C as non-corrosive cationic emulsifiers in Marine Coatings, a bio-mass dispersant with unique solubility parameters in Oil Field applications. Mix CS 445C/CS 525C with weak organic acids to enhance performance in aqueous or non-aqueous systems through an in-situ replacement of the counter-ion. The unique hard water tolerance of MASON CS 445C/CS 525C imparts differentiated performance in formulated aqueous products.
