Description

Siloxanes and Silicones, di-Me, polymers with Me silsesquioxanes, hydroxy-terminated, reaction products with Me Et ketone O,O',O''-(methylsilylidyne)trioxime and trimethoxy[3-(oxiranylmethoxy)propyl]silane is a specialized, multi-functional silicone-based hybrid polymer designed for advanced material science applications. This compound is engineered to deliver superior performance as a reactive intermediate or cross-linking agent, offering enhanced thermal stability, chemical resistance, and adhesion properties. It is critically needed by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in the production of high-performance composites and electronic encapsulants.

Application

• As a key cross-linking agent or chain extender in the formulation of high-temperature resistant silicone resins and rubbers.
• Enhancing the adhesion and durability of specialty industrial and protective coatings.
• Formulating advanced adhesives and sealants with improved flexibility and environmental resistance.
• Acting as a surface modifier or coupling agent in composite materials to improve filler-matrix bonding.
• Used in the production of potting compounds and encapsulants for electronic components.
• As a reactive intermediate in the synthesis of other functionalized silicone polymers and silsesquioxane hybrids.
• Potential use in creating release coatings and anti-fouling surfaces.

Quality Control

Our production of this advanced silicone hybrid adheres to strict quality management systems. Each batch is characterized using advanced analytical techniques to ensure consistency in functionality, viscosity, and reactive group content. A comprehensive Certificate of Analysis (COA) detailing key parameters is provided with every shipment to guarantee it meets your specific formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
