Q1: What is the primary function of DOWSIL 236 in coating and ink formulations?
A: DOWSIL 236 is a water-based silicone dispersion designed to provide surface modification benefits—including improved slip, mar resistance, and substrate wetting—without significantly affecting gloss or intercoat adhesion in aqueous systems.
Q2: Is DOWSIL 236 compatible with acrylic and polyurethane dispersions?
A: Yes, DOWSIL 236 is formulated for broad compatibility with common waterborne polymer systems, including acrylics, styrene-acrylics, and aliphatic polyurethane dispersions, though compatibility testing under specific formulation conditions is recommended.
Q3: How should DOWSIL 236 be incorporated into a formulation?
A: It is typically added during the let-down stage under low-shear mixing to preserve dispersion integrity. Pre-dilution with water or a compatible co-solvent may aid uniform incorporation, especially in high-viscosity systems.
Q4: Does DOWSIL 236 require post-application curing to develop its full performance?
A: No, performance benefits such as surface lubricity and leveling are realized upon film formation and drying at ambient or moderate thermal conditions—no additional crosslinking or heat activation is needed.
