Description

Siloxanes And Silicones, Di-Me, Hydrogen-Terminated, Reaction Products With 2,2-Bis(1-Oxo-2-Propenyl)Oxymethyl-1,3-Propanediyl Diacrylate is a specialized reactive silicone intermediate designed for high-performance crosslinking applications. This compound matters for its unique ability to impart silicone-like properties such as flexibility, thermal stability, and hydrophobicity into advanced polymer networks. It is primarily needed by formulators in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as by manufacturers of specialty composites and release liners.

Application

• As a key crosslinking agent in UV-curable coatings and inks to enhance flexibility and surface properties.
• In the formulation of high-performance pressure-sensitive adhesives (PSAs) and sealants for improved weatherability.
• As a reactive modifier in silicone-based release liners and anti-adhesive coatings.
• For the synthesis of specialty silicone-acrylate hybrid polymers used in advanced composites.
• In the production of elastomers and molded rubber parts requiring enhanced thermal and chemical resistance.
• As an additive in electronic potting compounds and encapsulants to manage stress and provide moisture protection.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and batch-to-batch consistency. Quality is monitored through parameters such as viscosity, acrylate equivalent weight, silicone content, and residual monomer levels. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). This material is light-sensitive (store away from light) and may be susceptible to polymerization if contaminated or exposed to heat and initiators. Keep away from heat, sparks, and open flame.
