Description

Siloxanes And Silicones, Di-Me, 3-2-(Hydroxy-3-(1-Oxo-2-Propenyl)Oxypropoxypropyl Group-Terminated is a specialized, reactive silicone intermediate featuring terminal acrylate and hydroxyl functionalities. This unique bifunctional structure is critical for its role as a versatile crosslinker and modifier in advanced polymer synthesis. It is essential for formulators and manufacturers seeking to enhance the flexibility, adhesion, and durability of final products. Key industries that rely on this compound include high-performance coatings, advanced adhesives, and specialty elastomers.

Application

• UV-Curable Coatings & Inks: Acts as a reactive diluent and crosslinking agent to improve flexibility, scratch resistance, and adhesion to various substrates.
• Pressure-Sensitive Adhesives (PSAs): Used as a modifier to enhance tack, peel strength, and thermal stability of acrylic and silicone-based adhesive systems.
• Silicone Hybrid Polymers: Serves as a key building block for creating silicone-organic copolymers with tailored properties for release coatings and sealants.
• Fiber Optic Coatings: Imparts essential protective, flexible, and low-stress properties to primary and secondary coatings for optical fibers.
• 3D Printing Resins: Incorporated into formulations for stereolithography (SLA) and digital light processing (DLP) to reduce shrinkage and improve layer adhesion.
• Electronic Encapsulants: Modifies epoxy or silicone potting compounds to manage stress and improve resistance to thermal cycling and moisture.

Quality Control

Our production of this reactive silicone intermediate adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, acrylate equivalent weight, viscosity, and purity are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

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 / 59-77°F). Keep away from heat sources and incompatible materials such as strong oxidizing agents. Under these conditions, the product is typically stable. For long-term storage, consider under an inert atmosphere to prevent potential oxidation or moisture uptake.
