Q1: What is the primary function of MEM-7137R in coating and ink formulations?
A: MEM-7137R 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 improving gloss uniformity and substrate coverage.
Q2: Is MEM-7137R compatible with common water-based polymer systems?
A: Yes, MEM-7137R exhibits good compatibility with acrylics, styrene-acrylics, vinyl acetate copolymers, and polyurethane dispersions. Compatibility should be verified in the final formulation due to variations in pH, ionic strength, and surfactant package.
Q3: How should MEM-7137R be incorporated into a formulation?
A: It is recommended to add MEM-7137R during the let-down stage, after the main binder and pigments have been dispersed. Stir gently to avoid excessive air entrainment. Pre-dilution with water may improve incorporation in sensitive systems.
Q4: Does MEM-7137R affect film formation or drying behavior?
A: MEM-7137R typically does not interfere with film formation or significantly alter drying kinetics at recommended use levels. However, high addition rates may delay surface drying or impact intercoat adhesion, so dosage optimization is advised for each application.
Q5: Can MEM-7137R be used in food-contact or regulated applications?
A: MEM-7137R is not pre-approved for direct food-contact applications. Customers intending to use it in regulated end uses must conduct their own suitability assessment, including compatibility testing and regulatory review, in accordance with applicable local and regional requirements.
