Q1: What is the primary function of OFX-8468 in industrial coatings and inks?
A: OFX-8468 is a silicone polymer designed to enhance surface leveling, reduce cratering and orange peel, and improve substrate wetting—particularly on low-surface-energy substrates such as plastics and treated metals. It functions as a processing aid rather than a film-former.
Q2: Is OFX-8468 compatible with waterborne systems?
A: Yes, OFX-8468 is formulated for compatibility with both solvent-based and waterborne coating and ink systems. It disperses readily without requiring high-shear pre-mixing and remains stable across typical pH ranges used in aqueous formulations.
Q3: How does OFX-8468 differ from conventional silicone surfactants?
A: Unlike many reactive or high-migration silicone surfactants, OFX-8468 is a non-reactive, low-volatility silicone polymer with balanced surface activity and minimal impact on intercoat adhesion or overprintability—making it suitable for multi-layer industrial applications.
Q4: What are recommended handling and storage conditions?
A: Store in original unopened containers at temperatures between 5°C and 30°C, away from direct sunlight and sources of heat. Avoid prolonged exposure to freezing conditions. Containers should remain tightly sealed when not in use to prevent moisture uptake or contamination.
