Description

Siloxanes and Silicones, di-Me, Me hydrogen, reaction products with polyethylene glycol monoallyl ether, polymers with maleic anhydride and pentaerythritol, acryloyl-terminated is a specialized, multifunctional silicone-based polymer designed for high-performance applications. This compound matters for its unique combination of silicone fluid properties with reactive acrylate and polyether functionalities, enabling superior compatibility and cross-linking in demanding formulations. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for creating advanced release liners and pressure-sensitive adhesives where durability and surface activity are critical.

Application

• UV-Curable Coatings and Inks: Acts as a reactive diluent and modifier to enhance flexibility, abrasion resistance, and surface slip.
• Pressure-Sensitive Adhesives (PSAs): Imparts permanent or removable tack, improves wetting on low-energy surfaces, and enhances silicone release properties.
• Silicone Release Liners: Serves as a key component in radiation-curable release coatings for labels and graphic films.
• High-Performance Sealants and Elastomers: Used as an additive or cross-linker to improve weatherability, hydrophobicity, and mechanical properties.
• Fiber and Textile Treatments: Provides durable softness, water repellency, and fiber lubrication when incorporated into finishing formulations.
• Industrial Lubricants and Greases: Enhances thermal stability, reduces friction, and provides water resistance in specialty lubricant blends.
• Polymer Modification: Functions as a macromonomer or graft copolymer to introduce silicone segments into acrylic, polyester, or polyurethane systems.

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters monitored include acrylate equivalent weight, silicone content, viscosity, and residual monomer levels. Certificates of Analysis (COA) detailing these specifications are available upon request. Production follows ISO 9001 quality management systems, and the material can be supplied in grades suitable for industrial and specialty chemical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This material is light-sensitive and easily oxidized; prolonged exposure to air, heat, or UV light should be avoided to prevent premature polymerization or viscosity changes. For long-term storage, consider maintaining under an inert atmosphere such as nitrogen.
