Description

1,3-Bis(3-Chloropropyl)Tetrakis-(Trimethylsiloxy)Disiloxane, Tech-95 is a high-purity, organosilicon intermediate featuring a unique disiloxane backbone functionalized with chloropropyl and trimethylsiloxy groups. This compound is a critical building block for synthesizing advanced silicone polymers and specialty materials, offering precise control over cross-linking and surface modification. It is essential for manufacturers in the silicone elastomer, adhesive, and release coating industries who require reliable, high-performance raw materials for demanding applications.

Application

• Silicone Polymer Synthesis: A key monomer for creating custom silicone resins, elastomers, and rubbers with tailored mechanical and thermal properties.
• Cross-linking Agent: Used as a reactive cross-linker in heat-cured silicone systems (HCR) and liquid silicone rubbers (LSR) to enhance strength and durability.
• Surface Modification: Imparts hydrophobic and release characteristics to surfaces in coatings, textiles, and paper treatments.
• Adhesive & Sealant Formulation: Enhances adhesion, flexibility, and environmental resistance in high-performance silicone-based adhesives and sealants.
• Release Coating Production: Serves as a precursor for manufacturing durable release liners used in labels, tapes, and composite materials.
• Specialty Additive: Functions as a compatibilizer or property modifier in advanced composite and plastic formulations.
