Description

Siloxanes And Silicones, Di-Me, Polymers With Me Silsesquioxanes And Polypropylene Glycol Mono-Bu Ether is a specialized organosilicon copolymer that combines the properties of polydimethylsiloxane (PDMS), methyl silsesquioxanes, and polypropylene glycol. This engineered material offers a unique balance of silicone-based hydrophobicity, thermal stability, and organic polymer compatibility. It is a critical performance additive for formulators seeking to enhance surface properties, modify rheology, and improve processability in advanced industrial applications.

Application

• Coatings & Inks: Used as a flow and leveling agent, anti-cratering additive, and slip aid to improve surface finish and mar resistance.
• Personal Care & Cosmetics: Functions as an emollient, conditioning agent, and texturizer in hair care products, skin creams, and color cosmetics for a smooth, non-greasy feel.
• Industrial Lubricants & Release Agents: Serves as a component in high-temperature lubricants, mold release formulations, and anti-foam agents due to its thermal stability and low surface tension.
• Adhesives & Sealants: Acts as a modifier to enhance wetting, improve adhesion to low-energy surfaces, and provide internal lubrication during processing.
• Plastics & Elastomers: Employed as a processing aid and internal lubricant to reduce viscosity, prevent sticking, and improve dispersion of fillers.
• Textile & Fiber Treatment: Utilized as a softener and water repellent finish to impart a soft hand and durable performance to fabrics.

Quality Control

Our production of this specialty silicone copolymer adheres to strict quality management systems. Each batch is characterized for critical parameters including viscosity, refractive index, specific gravity, and non-volatile content to ensure batch-to-batch consistency. Certificates of Analysis (COA) documenting these specifications are available upon request. We support compliance with relevant global regulatory frameworks for industrial chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. For long-term storage, consider under an inert atmosphere to prevent viscosity changes.
