Masil® SF19

Clear, Honey Colored Liquid

MASIL SF 19 is a low toxicity silicone surfactant with high thermal stability combining the advantages of dimethyl silicone fluids with conventional, nonionic surfactants. This product has a polydimethyl -siloxane backbone modified via the chemical attachment of polyoxyalkylene chains. MASIL SF 19 provides reduced surface tension in aqueous and non-aqueous systems, lubricity, and flow and leveling in a variety of coatings, textile, plastic and personal care applications.
