Description

Siloxanes And Silicones, Di-Me, Hydroxy-Terminated, Reaction Products With Me Hydrogen Siloxanes is a specialized reactive silicone intermediate. This compound is valued for its unique combination of hydroxy and hydride (Si-H) functionalities, enabling it to act as a crosslinker and chain extender in silicone polymer synthesis. It is essential for manufacturers requiring precise control over polymer architecture, viscosity, and final material properties. Key industries that utilize this material include advanced silicone elastomers, adhesives, release coatings, and tailored silicone fluids.

Application

• Crosslinking Agent for HTV & RTV Silicone Rubbers: Imparts specific cure characteristics and enhances mechanical properties in high-temperature vulcanizing (HTV) and room-temperature vulcanizing (RTV) elastomers.
• Intermediate for Silicone Resin Modification: Used to introduce branching or to modify the solubility and compatibility of silicone resins for coatings and composites.
• Key Component in Addition-Cure Systems: Serves as a core hydride-functional crosslinker in platinum-catalyzed addition cure formulations for liquid silicone rubber (LSR) and heat-cured rubbers.
• Synthesis of Specialty Silicone Fluids & Oils: Employed in creating custom silicone polymers with targeted molecular weights and functional end-groups for lubricants, surfactants, and dielectric fluids.
• Adhesive & Sealant Formulations: Enhances adhesion, cohesion, and environmental resistance in high-performance silicone-based adhesives and sealants.
• Release Coating Production: Acts as a reactive modifier in silicone release coatings for papers, films, and labels, controlling release force.

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 material is sensitive to strong alkali and organic solvents; keep away from such incompatible substances. Under recommended storage conditions, the product remains stable. For long-term storage, consider maintaining under a dry, inert atmosphere (e.g., nitrogen) to preserve reactivity.
