Q1: What is the primary function of MEM-2664 in water-based formulations?
A: MEM-2664 is a nonionic silicone emulsion designed to provide surface modification, improved slip and leveling, reduced surface tension, and enhanced substrate wetting—particularly in aqueous systems such as coatings, adhesives, and textile treatments.
Q2: Is MEM-2664 compatible with anionic and cationic additives?
A: As a nonionic silicone emulsion, MEM-2664 generally exhibits good compatibility with many anionic and cationic components; however, stability should be verified experimentally in each specific formulation due to potential interactions with high-charge-density surfactants or coagulants.
Q3: How should MEM-2664 be incorporated into a formulation to ensure optimal performance?
A: It is recommended to add MEM-2664 during the let-down stage under moderate agitation. Pre-dilution with water may aid dispersion, and avoiding high-shear mixing immediately after addition helps preserve emulsion integrity. Dosage depends on formulation requirements but is typically used at low concentrations for effective surface effects.
Q4: Can MEM-2664 be used in applications requiring FDA compliance for indirect food contact?
A: MEM-2664 is not pre-approved for direct or indirect food-contact applications under FDA regulations. Customers intending such use must conduct full regulatory evaluation—including compatibility testing and migration assessment—as part of their own compliance process.
