DOW DOWSIL SZ-1605 Fluid

DOW DOWSIL SZ-1605 Fluid is a low-viscosity, methyl-terminated polydimethylsiloxane (PDMS) silicone fluid from Dow’s DOWSIL™ portfolio. Designed for formulators requiring excellent thermal stability, low surface tension, and compatibility with organic polymers, it serves as a base fluid in lubricants, personal care emulsions, and industrial coatings. Non-volatile and chemically inert, it enhances slip, leveling, and hydrophobicity without compromising clarity or odor.
