Q1: What is the primary function of DOWSIL BY 11-007 in industrial coatings and inks?
A: DOWSIL BY 11-007 is a silicone-based additive designed to improve substrate wetting, reduce surface defects such as craters and orange peel, and enhance leveling and gloss uniformity in solvent-borne and high-solids coating systems.
Q2: Is DOWSIL BY 11-007 compatible with UV-curable formulations?
A: Yes, it is generally compatible with UV-curable acrylate systems and does not significantly inhibit photopolymerization when used at recommended dosage levels. However, compatibility should be verified in the final formulation due to potential interactions with specific photoinitiators or monomers.
Q3: How should DOWSIL BY 11-007 be incorporated into a formulation?
A: It is typically added during the let-down stage under moderate agitation. Pre-dilution in a compatible solvent may aid dispersion, especially in low-solvent or high-viscosity systems. Avoid high-shear mixing immediately after addition to prevent excessive air entrapment.
Q4: Does DOWSIL BY 11-007 affect recoatability or intercoat adhesion?
A: When used within the recommended dosage range, it generally does not impair intercoat adhesion. However, overuse may lead to surface migration and interfere with subsequent coating layers—formulators are advised to evaluate adhesion performance in their specific system.
