Description

Siloxanes And Silicones, Di-Me, Polymers With Me Silsesquioxanes, Polyethylene-Polypropylene Glycol And Polyethylene-Polypropylene Glycol Mono-Bu Ether is a sophisticated, multi-functional organosilicon copolymer engineered to deliver unique surface-active and compatibilizing properties. This compound matters for industrial formulators seeking to enhance performance in demanding applications by combining the thermal stability and hydrophobicity of silicones with the surfactant characteristics of polyethers. Key industries that need this advanced material include coatings, personal care, and polyurethane foam manufacturing, where it acts as a critical additive for foam stabilization, surface modification, and flow control.

Application

• Polyurethane Foam Stabilizer: Acts as a key surfactant in flexible and rigid polyurethane foam production, controlling cell structure and ensuring uniform foam rise.
• Coatings & Inks Additive: Improves substrate wetting, flow, and leveling while reducing surface defects like craters and orange peel in solvent-based and high-solid coatings.
• Personal Care & Cosmetics: Functions as an emollient and conditioning agent in hair care and skincare formulations, providing a smooth, non-greasy feel.
• Industrial Surfactant: Serves as a compatibilizer and wetting agent in agricultural formulations, textile processing, and metalworking fluids.
• Adhesive & Sealant Modifier: Enhances adhesion to low-energy surfaces and improves the rheological profile of silicone-modified polymers.
• Release Agent Component: Used in formulations for mold release applications, particularly where non-transfer and multiple releases are required.

Quality Control

Our production of this specialty silicone copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. While specific grades are tailored to application needs, all materials undergo rigorous in-process and final testing, which may include analysis of viscosity, hydroxyl value, ethylene oxide content, and silicone content. A Certificate of Analysis (COA) detailing key specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
