Q1: What is the primary function of MEM-1785 in coating and ink formulations?
A: MEM-1785 is a non-ionic, anionic-stabilized silicone emulsion designed to provide surface tension reduction, improved substrate wetting, enhanced leveling, and reduced pinholing—particularly in water-based architectural coatings, industrial finishes, and flexographic or gravure inks.
Q2: Is MEM-1785 compatible with common water-based polymer systems such as acrylics, vinyl acetate copolymers, and styrene-butadiene dispersions?
A: Yes, MEM-1785 exhibits broad compatibility with typical waterborne resin systems. It is formulated for stable incorporation without causing coagulation or viscosity instability when added during the let-down stage, provided standard addition protocols and pH conditions (typically pH 6–9) are maintained.
Q3: How should MEM-1785 be incorporated into a formulation to ensure optimal performance and stability?
A: It is recommended to add MEM-1785 during the final let-down stage, after pigments and thickeners have been dispersed, under moderate agitation. Avoid high-shear mixing post-addition and minimize exposure to strong electrolytes or extreme pH shifts to preserve emulsion integrity.
Q4: Does MEM-1785 contribute to foam generation or affect defoamer selection in formulations?
A: While MEM-1785 itself is not highly foaming, its surface-active nature may influence foam behavior. Formulators should evaluate foam control holistically and may need to adjust defoamer type or dosage—especially when combining with other surfactants or high-shear processing steps.
