Q1: What is the primary function of MEM-8031 in coating and ink formulations?
A: MEM-8031 is a non-ionic, anionic-stabilized silicone emulsion designed to provide surface leveling, substrate wetting, and foam control in water-based coatings, inks, and graphic arts systems. It helps reduce surface defects such as craters, orange peel, and pinholes while maintaining compatibility with common acrylic and polyurethane dispersions.
Q2: Is MEM-8031 compatible with cationic or high-solids systems?
A: MEM-8031 is formulated for use in neutral to slightly alkaline, anionic-stabilized aqueous systems. It is generally not recommended for strongly cationic or highly acidic formulations due to potential destabilization. Compatibility testing under actual formulation conditions—including pH, ionic strength, and shear—is advised before full-scale integration.
Q3: How should MEM-8031 be incorporated into a formulation to ensure optimal performance?
A: For best results, MEM-8031 should be added during the let-down stage—after pigments and primary binders are dispersed—under moderate agitation. Avoid high-shear mixing post-addition to prevent emulsion breakdown. Dosage typically ranges from 0.1% to 2% by weight of total formulation, depending on desired surface effects and system sensitivity.
