Q1: What is the primary function of MEM-1664 in industrial coatings and inks?
A: MEM-1664 is a non-ionic, anionic-stabilized silicone emulsion designed to provide surface leveling, substrate wetting, and foam control in water-based systems. It helps reduce surface defects such as craters, orange peel, and pinholes while improving gloss uniformity and substrate adhesion.
Q2: Is MEM-1664 compatible with common water-based polymer systems like acrylics, vinyl acetate, and styrene-butadiene dispersions?
A: Yes, MEM-1664 demonstrates broad compatibility with many anionic and non-ionic aqueous polymer dispersions. It is typically added during the let-down stage and remains stable under standard formulation pH conditions (pH 6–9), though compatibility testing under specific shear, temperature, and ionic strength conditions is recommended.
Q3: How should MEM-1664 be incorporated into a formulation to ensure optimal performance?
A: For best results, MEM-1664 should be added gradually with gentle mixing—avoid high-shear dispersion unless validated for the target system. Pre-dilution with water or a compatible co-solvent may aid incorporation. Dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight of the total formulation.
Q4: Does MEM-1664 contribute to long-term storage stability of formulated products?
A: MEM-1664 is formulated to support colloidal stability in typical water-based systems when used within recommended dosage ranges and pH windows. However, long-term stability can be influenced by other formulation components (e.g., biocides, surfactants, electrolytes), so accelerated storage testing under intended conditions is advised.
