Description

Siloxanes And Silicones, Di-Me, Hydrogen-Terminated, Reaction Products With Polyethylene-Polypropylene Glycol Allyl Bu Ether is a specialized organomodified silicone copolymer designed to impart unique surface-active and compatibilizing properties. This compound matters for formulators seeking to enhance performance in demanding applications where standard silicones may fail, such as in polar media or reactive systems. Key industries that need this advanced material include polyurethane foam manufacturing, coatings, adhesives, and personal care, where it acts as a surfactant, stabilizer, or reactive intermediate.

Application

• Polyurethane Foam Stabilizer: Acts as a key surfactant in the production of flexible and rigid polyurethane foams, controlling cell structure and improving foam stability.
• Coatings & Inks Additive: Enhances flow, leveling, and substrate wetting in solvent-based and high-solid coatings, while reducing surface defects.
• Adhesive & Sealant Modifier: Improves adhesion to low-energy surfaces and provides internal lubrication in silicone-modified polymers and sealants.
• Personal Care Ingredients: Used in hair care and skincare formulations as an emollient and conditioning agent, providing softness without greasiness.
• Industrial Surfactant: Serves as a compatibilizer and emulsifier in agricultural formulations, textile processing aids, and lubricant additives.
• Reactive Intermediate: The hydrogen-terminated and allyl ether groups allow for further chemical modification via hydrosilylation or other reactions for custom polymer synthesis.

Quality Control

Our production of this organomodified silicone adheres to strict quality management systems. Each batch is characterized for critical parameters including silicone content, polyether block ratio, viscosity, and reactive hydrogen value to ensure consistent performance. Certificates of Analysis (COA) documenting these specifications are provided with every shipment. We support compliance with relevant frameworks for industrial chemicals, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and potential oxidation. Keep away from strong oxidizing agents.
