Description

Siloxanes And Silicones, Di-Me, 6-Hydroxyhexyl Group-Terminated is a specialized organosilicon compound featuring a reactive hydroxyhexyl terminal group on a polydimethylsiloxane (PDMS) backbone. This bifunctional structure, combining the flexibility and hydrophobicity of silicone with a primary alcohol end-group, makes it a valuable reactive intermediate and modifier in advanced polymer synthesis. It is essential for manufacturers in the personal care, coatings, adhesives, and specialty elastomer industries seeking to enhance product performance through silicone hybrid technology.

Application

• Reactive Silicone Intermediate: Serves as a key building block for synthesizing silicone polyethers, silicone acrylates, and other silicone-organic hybrid polymers.
• Personal Care & Cosmetics: Used in the formulation of high-performance hair conditioners, skin creams, and sunscreens to provide superior softness, lubricity, and water resistance.
• Release Coatings & Pressure-Sensitive Adhesives (PSAs): Functions as a reactive modifier to tailor release force and adhesion properties in silicone release liners and tapes.
• Coating & Ink Additives: Imparts slip, mar resistance, and improved surface wetting in industrial and graphic arts coatings.
• Elastomer & Sealant Modification: Incorporated into silicone or organic rubber formulations to modify crosslink density, flexibility, and surface characteristics.
• Fiber & Textile Treatment: Applied as a softener and water-repellent finishing agent for synthetic and natural fibers.

Quality Control

Our Siloxanes And Silicones, Di-Me, 6-Hydroxyhexyl Group-Terminated is produced under a stringent quality management system. Each batch is tested to ensure consistent performance as a reactive intermediate, with key parameters including hydroxyl value, viscosity, and silicone content. Certificates of Analysis (COA) detailing purity and specifications are available upon request to support your quality assurance and regulatory compliance needs.

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/59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and potential viscosity changes or reactivity loss.
