Description

Siloxanes And Silicones, Di-Me, Hydroxy-Terminated, Ethers With Polyethylene-Polypropylene Glycol Mono-Bu Ether is a specialized organomodified silicone surfactant. This compound is engineered to provide unique surface-active properties, combining the flexibility and thermal stability of silicone with the hydrophilicity and solubility characteristics of polyether chains. It is a critical performance additive for formulators seeking to enhance wetting, leveling, and compatibility in complex systems. Key industries that rely on this material include coatings, personal care, polyurethane foam production, and industrial lubricants.

Application

• Coatings & Inks: Acts as a powerful wetting, leveling, and flow control agent to eliminate surface defects and improve substrate adhesion.
• Polyurethane Foams: Serves as a key cell opener and stabilizer in flexible slabstock and molded foam formulations, ensuring uniform cell structure.
• Personal Care Products: Used in hair conditioners, skin creams, and antiperspirants as an emollient and conditioning agent that provides a smooth, non-greasy feel.
• Industrial Lubricants & Release Agents: Enhances lubricity and acts as a mold release agent in plastic and rubber manufacturing processes.
• Adhesives & Sealants: Improves spreadability, substrate wetting, and moisture resistance in various adhesive systems.
• Agricultural Adjuvants: Functions as a surfactant to improve the spreading and retention of pesticides and herbicides on plant surfaces.
• Textile Processing: Employed as a softener and lubricant for fibers, improving handle and reducing friction during weaving.

Quality Control

Our organomodified silicone polyethers are manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including verification of hydroxyl value, viscosity, and polyether content. Certificates of Analysis (COA) documenting key specifications are available for every shipment. We support compliance with relevant global regulatory frameworks, 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.
