Q1: What is the primary function of DOWSIL BY 16-606 Silicone in coating and ink formulations?
A: DOWSIL BY 16-606 Silicone functions primarily as a surface additive to improve substrate wetting, reduce surface tension, and enhance leveling and gloss uniformity—without significantly affecting intercoat adhesion or recoatability.
Q2: Is DOWSIL BY 16-606 Silicone compatible with waterborne and solventborne systems?
A: Yes, it demonstrates broad compatibility across both waterborne and solventborne coatings, inks, and overprint varnishes—including acrylic, polyurethane, and alkyd-based chemistries—though compatibility testing under specific formulation conditions is recommended.
Q3: How should DOWSIL BY 16-606 Silicone be incorporated into a formulation?
A: It is typically added during the let-down stage, after pigments and resins are dispersed, and mixed under moderate shear. Pre-dilution with a compatible carrier solvent or resin solution may aid uniform dispersion, especially in low-solids systems.
Q4: Does DOWSIL BY 16-606 Silicone affect film hardness or drying behavior?
A: When used at recommended dosage levels, it generally has minimal impact on final film hardness or air-dry/cure kinetics; however, excessive addition may delay surface dry or interfere with crosslinking in certain reactive systems.
