Q1: What is the primary function of MEM-0037 in coating and ink formulations?
A: MEM-0037 is a non-ionic, anionic-stabilized silicone emulsion designed to provide surface leveling, substrate wetting, and foam control in water-based coatings, inks, and adhesives. It helps reduce surface defects such as craters, orange peel, and pinholes while enhancing gloss uniformity and substrate coverage.
Q2: Is MEM-0037 compatible with common water-based polymer systems?
A: Yes, MEM-0037 demonstrates broad compatibility with acrylics, vinyl acetate copolymers, styrene-acrylic dispersions, and polyurethane dispersions. It is formulated for stability in neutral to mildly alkaline pH ranges (typically pH 6–9) and generally remains stable in the presence of common thickeners and coalescing agents.
Q3: How should MEM-0037 be incorporated into a formulation?
A: MEM-0037 is typically added during the let-down stage, after high-shear dispersion of pigments and fillers. It should be diluted with water or formulation water prior to addition and mixed under moderate agitation to ensure uniform distribution. Avoid high-shear mixing post-addition to prevent potential emulsion destabilization.
Q4: Does MEM-0037 affect film formation or drying behavior?
A: MEM-0037 is designed to minimize interference with film formation. Its low-volatility silicone components remain at the air–film interface, supporting surface optimization without significantly retarding water evaporation or coalescence. Drying times remain largely unaffected when used at recommended dosage levels.
