Description

1,3,5,7,9,11,14-Hepta-Isooctyltricyclo(7.) Heptasiloxane-Endo-3,7,14-Triol, 95% is a high-purity, branched organosilicon compound with a unique tricyclic heptasiloxane core structure. This specialized chemical serves as a versatile building block and performance additive, offering enhanced compatibility and reactivity due to its multiple hydroxyl and isooctyl functional groups. It is primarily sought by R&D and production teams in the advanced materials, specialty polymers, and silicone modification sectors for developing novel products with tailored surface and bulk properties.

Application

• Silicone Resin & Polymer Modification: Acts as a reactive intermediate or cross-linking agent to introduce branching, improve toughness, or modify the hydrophobicity/hydrophilicity balance of silicone-based polymers.
• Surface Treatment & Coatings: Used to formulate advanced surface treatments, primers, or release coatings where its structure can enhance adhesion to difficult substrates or create specific surface energies.
• Specialty Additives: Functions as a compatibilizer or performance additive in composite materials, helping to disperse fillers or improve interfacial bonding between organic and inorganic phases.
• Lubricant & Grease Formulation: Employed in the synthesis of high-performance silicone-based lubricants and greases, contributing to thermal stability and low-temperature properties.
• Pharmaceutical & Cosmetic Intermediates: Serves as a key synthetic intermediate for producing specialized siloxane derivatives used in controlled-release systems or personal care product formulations.
• Adhesive & Sealant Precursor: Utilized in the development of high-performance silicone adhesives and sealants, where its multi-functional nature can influence cure kinetics and final elastomer properties.
