Q1: What is the primary function of MEM-0347G in water-based formulations?
A: MEM-0347G is a nonionic, anionic-stable silicone emulsion designed to provide surface softening, slip enhancement, and improved substrate compatibility in aqueous systems such as coatings, adhesives, and textile finishes.
Q2: Is MEM-0347G compatible with common water-based polymer systems like acrylics or styrene-butadiene?
A: Yes, MEM-0347G exhibits good compatibility with a broad range of waterborne polymers, including acrylic, vinyl acetate, and styrene-butadiene dispersions, and is formulated to minimize destabilization risks in typical industrial formulation conditions.
Q3: How should MEM-0347G be incorporated into a formulation to ensure optimal performance and stability?
A: It is recommended to add MEM-0347G during the let-down stage, under moderate agitation, after the main polymer phase is fully dispersed. Avoid high-shear mixing at elevated temperatures to preserve emulsion integrity and functional performance.
Q4: Can MEM-0347G be used in applications requiring low foam generation?
A: Yes, MEM-0347G is formulated to deliver effective surface modification with inherently low foaming tendency, making it suitable for applications where foam control is critical—such as roll-coating or high-speed coating processes.
Q5: What storage conditions are recommended to maintain product stability?
A: Store MEM-0347G in its original sealed container at temperatures between 5 °C and 30 °C, away from freezing and prolonged exposure to direct sunlight or excessive heat, to preserve emulsion stability and performance consistency.
