Description

(2,4,6,8-Tetramethylcyclotetrasiloxane-2,4,6,8-Tetrayl)Tetrakis(Propane-1,3-Diyl) Tetraacrylate CAS NO 71550-64-6 is a specialized, multi-functional acrylate monomer featuring a core cyclotetrasiloxane ring. This compound is valued for its ability to introduce both siloxane properties and polymerizable acrylate groups into advanced material formulations. It is primarily sought by R&D and production teams in the photopolymer, advanced coating, and specialty silicone resin sectors for developing high-performance, cross-linked networks.

Application

• Photopolymer & UV-Curable Systems: Acts as a high-functionality cross-linker to enhance cure speed, hardness, and chemical resistance in coatings, inks, and 3D printing resins.
• Specialty Silicone-Modified Polymers: Serves as a key building block for synthesizing hybrid organic-silicone polymers with improved flexibility, thermal stability, and surface properties.
• Release Coatings & Pressure-Sensitive Adhesives (PSAs): Used to formulate silicone-acrylate hybrids that offer controlled release characteristics or tailored adhesive performance.
• Optical & Electronic Encapsulants: Incorporated into clear, durable resins for protecting LEDs, sensors, and electronic components due to potential thermal and environmental stability.
• High-Performance Coatings: Imparts mar-resistance, weatherability, and low surface energy to industrial and automotive coatings.
• Dental & Biomedical Materials: Investigated for use in biocompatible, photocurable composites and implants where specific mechanical and surface properties are required.

Quality Control

Our production of this specialty acrylate follows strict quality protocols to ensure batch-to-batch consistency and high purity. Quality is verified through analytical methods including HPLC, GC, and NMR to confirm identity, assay, and monitor for impurities. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. To prevent premature polymerization, store under an inert atmosphere if specified and avoid contamination with peroxides or other free radical initiators.
