Description

Siloxanes And Silicones, Me 3,3,3-Trifluoropropyl, Me Vinyl, Hydroxy-Terminated is a specialized fluorosilicone polymer featuring a unique combination of vinyl, trifluoropropyl, and terminal hydroxy groups. This molecular architecture provides a balance of chemical resistance, low surface energy, and reactivity, making it a critical intermediate for high-performance materials. It is essential for formulators and manufacturers in the aerospace, automotive, and specialty coatings industries seeking to enhance product durability and performance under extreme conditions.

Application

• High-Performance Sealants & Adhesives: Serves as a key reactive intermediate for formulating fluorosilicone sealants and adhesives that offer exceptional resistance to fuels, oils, solvents, and extreme temperatures.
• Specialty Release Coatings: Used in the synthesis of release coatings for industrial applications requiring non-stick properties against aggressive chemicals.
• Advanced Elastomers: A vital building block for cross-linked fluorosilicone elastomers (FVMQ) used in O-rings, gaskets, and diaphragms in demanding automotive and aerospace environments.
• Surface Modification: Employed to modify surface properties of materials, imparting water and oil repellency (oleophobicity) and release characteristics.
• Pharmaceutical & Medical Device Coatings: Potential use in developing biocompatible, drug-eluting, or low-friction coatings for medical devices, subject to appropriate regulatory compliance.
• Additive for Plastics & Composites: Acts as a processing aid or property modifier in engineering plastics and composites to improve lubricity and chemical resistance.

Quality Control

Our fluorosilicone intermediates are manufactured under strict quality systems to ensure batch-to-batch consistency and performance. Quality is verified through a suite of analytical tests including determination of hydroxyl value, vinyl content, viscosity, and refractive index. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and premature reaction. Separate from strong oxidizing agents.
