Q1: What is the primary function of DOWSIL 92-023 in coating and ink formulations?
A: DOWSIL 92-023 is a silicone-based surface additive designed to improve substrate wetting, reduce surface defects (e.g., craters and orange peel), and enhance leveling and slip performance in solventborne and high-solids coatings, as well as printing inks.
Q2: Is DOWSIL 92-023 compatible with common resin systems such as acrylics, polyurethanes, and alkyds?
A: Yes — DOWSIL 92-023 demonstrates broad compatibility with major binder types including acrylics, polyurethanes, alkyds, and epoxy systems. Compatibility should be verified in the final formulation due to potential interactions with catalysts or reactive components.
Q3: How should DOWSIL 92-023 be incorporated into a formulation?
A: It is typically added during the let-down or post-addition stage under low-shear conditions. Pre-dilution in a compatible solvent may aid dispersion. Avoid high-shear mixing that could degrade silicone integrity or cause re-agglomeration.
Q4: Does DOWSIL 92-023 affect intercoat adhesion or overcoatability?
A: When used within recommended dosage ranges, DOWSIL 92-023 generally does not impair intercoat adhesion. However, excessive addition may lead to surface enrichment and potential adhesion issues — formulation optimization and adhesion testing are advised for critical applications.
Q5: Can DOWSIL 92-023 be used in food-contact or pharmaceutical-related coatings?
A: DOWSIL 92-023 is not pre-approved for direct food-contact applications. Its use in regulated environments requires full evaluation against applicable regional requirements and end-use compliance testing by the formulator or end user.
