Description

Siloxanes And Silicones, Di-Me, 3-Hydroxypropyl Group-Terminated, Diethers With Polyethylene Glycol Monoacrylate is a specialized reactive silicone intermediate, uniquely engineered with both hydroxypropyl and polyethylene glycol monoacrylate functional groups. This dual functionality is critical for formulators seeking to create advanced materials with enhanced compatibility, adhesion, and cross-linking capabilities. It is primarily used by R&D chemists and production engineers in the personal care, coatings, adhesives, and advanced polymer industries to develop high-performance, tailored products.

Application

• UV-Curable Coatings & Inks: Acts as a reactive diluent and modifier to improve flexibility, adhesion to low-energy surfaces, and weatherability in radiation-curable systems.
• Personal Care & Cosmetic Products: Serves as a key ingredient in silicone acrylate copolymers for hair fixatives, sunscreens, and skin care products, providing film-forming properties with a soft, non-tacky feel.
• Pressure-Sensitive Adhesives (PSAs): Incorporated to modify acrylic PSA systems, enhancing tack, peel strength, and compatibility with silicone release liners.
• Specialty Polymer Synthesis: Used as a macromonomer or cross-linker in the production of hybrid organic-silicone polymers, gels, and networks with tailored hydrophilicity and mechanical properties.
• Fiber & Textile Treatment: Imparts durable softness, moisture management, and anti-static properties when grafted onto synthetic or natural fibers.
• Release Coatings: Formulated into premium release liners for labels and tapes, offering controlled and stable release forces.

Quality Control

Our production of this advanced silicone intermediate adheres to strict quality management systems. Each batch is characterized using advanced analytical techniques to ensure consistency in functional group content, molecular weight distribution, and purity. Certificates of Analysis (COA) detailing key parameters such as acrylate equivalent weight, hydroxyl value, viscosity, and color are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect reactivity. For long-term storage, consider using an inert gas blanket (e.g., nitrogen). Keep away from heat and incompatible materials such as strong oxidizing agents.
