Q1: What is the primary function of DOWSIL 85 in coating and ink formulations?
A: DOWSIL 85 is a silicone elastomer additive designed to enhance surface slip, improve mar resistance, and reduce coefficient of friction in solvent-based, water-based, and UV-curable coatings and inks. It functions by migrating to the film surface during curing or drying to form a soft, elastic silicone-rich layer.
Q2: Is DOWSIL 85 compatible with common resin systems such as acrylics, polyurethanes, and epoxies?
A: Yes, DOWSIL 85 demonstrates broad compatibility with a range of thermosetting and thermoplastic resins, including acrylics, alkyds, polyurethanes, and epoxy-based systems. Compatibility should be verified in the final formulation due to potential interactions with catalysts, surfactants, or other additives.
Q3: How is DOWSIL 85 typically incorporated into a formulation?
A: It is generally added during the let-down or post-addition stage under moderate agitation. Pre-dilution in a compatible solvent or carrier resin may aid dispersion. Avoid high-shear mixing that could excessively break down the elastomeric particles and reduce performance.
Q4: Does DOWSIL 85 affect gloss or transparency in clear coat applications?
A: When used within recommended dosage ranges, DOWSIL 85 typically maintains high clarity and does not significantly impair gloss or transparency in clear coatings—making it suitable for premium decorative and protective finishes.
Q5: Can DOWSIL 85 contribute to improved substrate adhesion in multi-layer systems?
A: While not primarily an adhesion promoter, DOWSIL 85’s surface-modifying behavior can support intercoat adhesion in some stacked systems by optimizing interfacial energy—though adhesion performance must be validated empirically for each specific substrate and topcoat combination.
