Q1: What is the primary function of MEM-8035 in coating and ink formulations?
A: MEM-8035 is a non-ionic, anionic-stabilized silicone emulsion designed to provide surface leveling, substrate wetting, and foam control in water-based coatings, inks, and graphic arts systems. It helps reduce surface defects such as craters, orange peel, and pinholes while enhancing gloss uniformity and substrate coverage.
Q2: Is MEM-8035 compatible with common water-based polymer systems?
A: Yes, MEM-8035 exhibits broad compatibility with acrylics, styrene-acrylics, vinyl acetate copolymers, and polyurethane dispersions. Its stable emulsion profile minimizes the risk of coagulation or viscosity instability when added during let-down or post-addition stages—though compatibility testing under actual formulation conditions is recommended.
Q3: How should MEM-8035 be incorporated into a formulation for optimal performance?
A: MEM-8035 is typically added during the let-down stage after pigment grinding, with gentle mixing to avoid excessive shear. It is generally used at low concentrations—typically ranging from 0.1% to 2% by weight of total formulation—depending on substrate type, film thickness, and desired surface effect. Pre-dilution with water may improve dispersion in highly viscous systems.
Q4: Does MEM-8035 affect the drying or curing behavior of water-based systems?
A: MEM-8035 has minimal impact on water evaporation rate or film formation kinetics. As a non-reactive additive, it remains at the film-air interface and does not interfere with crosslinking mechanisms in coalescing or thermally cured systems. No significant delay in dry-to-touch or through-dry times is observed at recommended use levels.
