Description

(25-35% Nonafluorohexylmethylsiloxane) (65-75% Dimethylsiloxane) Copolymer, 8-12 Cst is a specialized fluorosilicone fluid engineered to deliver exceptional performance in demanding environments. This copolymer is valued for its unique combination of silicone flexibility and the oil, solvent, and chemical resistance imparted by the fluorinated side chains. It is a critical material for formulators and manufacturers in industries requiring durable, low-surface-energy additives and base fluids.

Application

• Release Agents & Mold Lubricants: Provides excellent non-stick properties and thermal stability for high-temperature molding processes, including rubber, plastics, and composites.
• Surface Modification & Additives: Used to impart water, oil, and soil repellency to coatings, textiles, and treated surfaces.
• Lubricants & Greases: Serves as a base fluid or additive in specialty lubricants for applications requiring chemical inertness and wide temperature performance.
• Defoamers & Antifoams: Effective in aggressive chemical and hydrocarbon-based systems where conventional silicones may fail.
• Personal Care & Cosmetics: Acts as a water-resistant, non-greasy emollient and texture enhancer in high-performance skincare and color cosmetics.
• Electrical/Electronic Encapsulants: Used as a modifying agent in potting compounds and gels to enhance moisture resistance and dielectric properties.
