Description

Siloxanes And Silicones, Di-Me, Hydroxy-Terminated, Polymers With n-3-(Dimethoxymethylsilyl)Propyl-1,2-Ethanediamine And Polyethylene-Polypropylene Glycol is a specialized organomodified silicone polymer engineered for advanced performance. This compound is valued for its unique hybrid structure, combining the flexibility and thermal stability of silicone with the hydrophilic and surfactant properties of polyether segments. It serves as a critical functional additive and reactive intermediate for formulators in demanding industrial sectors. Key industries that rely on this material include coatings, adhesives, sealants, elastomers (CASE), and polyurethane manufacturing.

Application

• Polyurethane Foam Stabilizer: Acts as a key surfactant in the production of flexible, rigid, and molded polyurethane foams, ensuring uniform cell structure and stability.
• Coatings & Inks Additive: Enhances flow, leveling, and substrate wetting in high-performance coatings, paints, and printing inks, while reducing surface defects.
• Adhesive & Sealant Modifier: Improves adhesion, flexibility, and moisture resistance in silicone-modified polymer (SMP) sealants and pressure-sensitive adhesives.
• Fiber & Textile Treatment: Used as a softener and finishing agent to impart durable softness, lubricity, and water repellency to synthetic and natural fibers.
• Personal Care & Cosmetics: Functions as an emollient and conditioning agent in hair care and skincare formulations, providing a smooth, non-greasy feel.
• Plastic & Rubber Additive: Serves as an internal lubricant and processing aid to improve mold release and surface finish in engineered plastics and rubber compounds.
• Reactive Intermediate: Utilized in the synthesis of more complex silicone copolymers and graft polymers due to its terminal hydroxyl and alkoxysilyl functional groups.

Quality Control

Our production of this organomodified silicone polymer adheres to stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent performance, including verification of hydroxyl value, viscosity, specific gravity, and polyether content. Certificates of Analysis (COA) detailing these parameters are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH, and can tailor specifications to meet specific customer or application standards.

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). 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 product performance. Keep away from strong oxidizing agents.
