Description

Siloxanes and silicones, di-Me, mono[3-[(2-methyl-1-oxo-2-propenyl)oxy]propyl] group-terminated polymers with Bu methacrylate, 2-ethylhexyl acrylate and Me methacrylate is a specialized, multi-functional silicone-acrylic hybrid polymer designed for high-performance applications. This compound matters for its unique ability to combine the flexibility, thermal stability, and surface activity of silicones with the durability, adhesion, and film-forming properties of acrylics. It is primarily needed by formulators in the coatings, adhesives, and advanced material sectors seeking to enhance product performance, weather resistance, and compatibility.

Application

• High-Performance Coatings: Used as a key additive or resin modifier in industrial, automotive, and architectural coatings to improve flexibility, mar resistance, and weatherability.
• Pressure-Sensitive Adhesives (PSAs): Enhances tack, peel strength, and high-temperature performance in specialty tape and label formulations.
• Release Coatings: Serves as a critical component in silicone-modified release liners for labels and graphic films.
• Plastics and Elastomer Modification: Incorporated as a processing aid or impact modifier to improve surface slip and reduce friction in polymer compounds.
• UV-Curable Systems: The methacryloyloxypropyl group-terminated structure makes it reactive and suitable for use in UV-curable inks, coatings, and 3D printing resins.
• Waterborne Dispersions: Utilized to develop stable, silicone-acrylic hybrid emulsions for environmentally friendly coating systems.

Quality Control

Our silicone-acrylic hybrid polymers undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters monitored include viscosity, solids content, acid value, and the degree of functionalization. Certificates of Analysis (COA) detailing specific lot results are available upon request. Our manufacturing processes adhere to ISO 9001 quality management principles.

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). Keep away from strong acids and organic solvents. For long-term storage, consider under an inert atmosphere to prevent premature cross-linking or viscosity increase.
