Description

Silane, Dichlorodimethyl-, Polymer With Trichlorophenylsilane is a specialized organosilicon copolymer designed for advanced material science applications. This product is valued for its ability to impart unique surface properties and enhance the performance of composite materials. It is primarily utilized by manufacturers in the silicone resin, specialty coating, and high-performance adhesive industries seeking to modify surface energy and improve adhesion.

Application

• As a key intermediate or additive in the synthesis of modified silicone resins for high-temperature and protective coatings.
• As a surface treating agent for inorganic fillers (e.g., silica, glass) to improve compatibility and dispersion in polymer matrices.
• In the formulation of release coatings and pressure-sensitive adhesives to control adhesion properties.
• As a coupling agent in fiber-reinforced composites to enhance the interfacial bond between glass or mineral fibers and the polymer resin.
• For the development of water-repellent and anti-corrosion coatings on metal, glass, or concrete surfaces.
• In the production of silicone-based encapsulants and sealants with tailored mechanical and chemical resistance.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Quality is monitored through parameters such as chlorine content, viscosity, and refractive index. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent hydrolysis and degradation. Recommended storage temperature is 2-25°C.
