SH-204 Polyether Modified Silicone Fluids
SH-204 (CAS 68937-55-3) is a versatile, nonionic polyether-modified silicone oil formulated for use in a wide range of industrial and specialty applications. With its unique siloxane-ether structure, SH-204 provides outstanding wetting, leveling, and anti-cratering performance, particularly in waterborne and solvent-based systems.
