Dow DOWSIL SM 8716 SR Emulsion is a high-performance nonionic emulsion of epoxy-functional silicone oil in the DOWSIL series, designed for textile finishing and paper sizing processes. It features excellent smooth modification, low yellowing and system compatibility, efficiently endowing cotton and other fiber materials with delicate and smooth texture
Efficient Smooth Modification - Endows fibers with delicate and smooth hand feel, enhancing product texture
Excellent Low Yellowing - Materials are not easy to yellow after finishing, maintaining bright natural color
Non-Ionic System Compatibility - Suitable for water-based formulations, good compatibility with organic resin emulsions
Easy Dilution & Processing - Can be directly diluted for use, suitable for padding, coating and other processe
Cotton Textile Finishing - Soft treatment of cotton fabrics, improving wearing and using comfort
Paper Sizing Additive - Sizing of cultural paper and packaging paper, enhancing paper strength and water resistance
Fiber Lubrication Modification - Lubrication in chemical fiber spinning process, reducing friction and improving processing efficiency
Knitted Fabric Finishing - Soft and wrinkle-resistant treatment of cotton knitted fabrics, optimizing hand feel and elasticity

Q1: What is the primary function of DOWSIL SM 8716 SR Silicone Oil in formulations?
A: DOWSIL SM 8716 SR is a reactive silicone fluid designed primarily as a surface modifier and release enhancer. It imparts improved slip, mar resistance, and substrate release properties to coatings, adhesives, and sealants—especially in high-performance industrial and automotive applications.
Q2: Is DOWSIL SM 8716 SR compatible with common crosslinking chemistries?
A: Yes—it contains reactive silane end-groups that enable covalent incorporation into silane-cured, moisture-cured, or condensation-cure systems. It is commonly used in RTV silicones, hybrid polymers (e.g., MS polymers), and silane-terminated polyethers, where it enhances both compatibility and long-term stability.
Q3: How does DOWSIL SM 8716 SR differ from non-reactive silicone oils?
A: Unlike non-reactive silicone oils—which may migrate or bloom over time—SM 8716 SR chemically bonds into the polymer matrix during cure. This results in more durable surface effects, reduced volatility, and improved resistance to extraction or leaching under thermal or mechanical stress.
Q4: What are typical handling and storage recommendations?
A: Store in tightly sealed containers under dry, cool conditions (below 30 °C) and protect from moisture ingress prior to use. Avoid prolonged exposure to humidity, as the reactive silane groups can undergo premature hydrolysis. Standard industrial PPE—including gloves and eye protection—is recommended during handling.
