Description

Siloxanes And Silicones, Di-Me, 3-Hydroxypropyl Group-Terminated, Diethers With Polyethylene Glycol Monomethacrylate is a specialized reactive silicone macromonomer designed for advanced material synthesis. This compound matters for its unique hybrid structure, combining the flexibility, thermal stability, and surface activity of silicones with the hydrophilicity and polymerizable functionality of polyethylene glycol methacrylate. It is essential for formulators and R&D chemists in the personal care, coatings, and advanced polymer industries seeking to create novel materials with tailored properties.

Application

• UV-Curable Coatings & Inks: Acts as a reactive modifier to enhance flexibility, adhesion, and surface slip in coatings for plastics, metals, and optical fibers.
• Personal Care & Cosmetic Products: Serves as a key ingredient in premium hair conditioners, skin creams, and sunscreens to provide exceptional softness, moisture retention, and a non-greasy feel.
• Silicone Hydrogel Contact Lenses: Used as a macromonomer to improve oxygen permeability (Dk) and surface wettability in next-generation soft contact lens materials.
• Pressure-Sensitive Adhesives (PSAs): Incorporated to modify tack, peel strength, and biocompatibility of medical tape and wearable device adhesives.
• Release Coatings: Functions as a crosslinkable component in low-surface-energy release liners for labels and industrial tapes.
• Fiber & Textile Treatment: Imparts durable softness, water repellency, and anti-static properties to synthetic and natural fibers.

Quality Control

Our production of this advanced silicone macromonomer adheres to a stringent quality management system. Each batch is characterized using advanced analytical techniques including GPC (Gel Permeation Chromatography) for molecular weight distribution, NMR (Nuclear Magnetic Resonance) for structural confirmation, and titration to determine reactive methacrylate content. Certificates of Analysis (COA) detailing purity, viscosity, and specific functional group content are provided to ensure consistency and performance for your critical formulations.

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). To prevent premature polymerization, it is recommended to store under an inert atmosphere (e.g., nitrogen) and to use appropriate inhibitors as supplied. Keep away from heat and open flames.
