Description

3-Methylbuten-2-Yl Methacrylate is a specialized methacrylate monomer with a reactive double bond and a branched prenyl-like structure. This compound is valued for its ability to introduce pendant isobutene groups into polymer chains, significantly influencing the final material's properties such as hydrophobicity, flexibility, and glass transition temperature. It is primarily sought by R&D chemists and formulators in the polymer and specialty chemical industries for creating advanced coatings, adhesives, and functional materials with tailored performance characteristics. The product is supplied under strict quality control to ensure batch-to-batch consistency for demanding industrial applications.

Application

• Advanced Polymer Synthesis: As a key monomer for producing specialty acrylic and methacrylic copolymers with enhanced properties.
• High-Performance Coatings: Used in formulations for automotive, industrial, and protective coatings to improve water resistance, adhesion, and durability.
• Pressure-Sensitive Adhesives (PSAs): Incorporated to modify tack, peel strength, and cohesion in adhesive tapes and labels.
• UV-Curable Resins & Inks: Serves as a reactive diluent or functional monomer in systems cured by ultraviolet light for rapid processing.
• Hydrophobic Surface Modifiers: Used to graft hydrophobic side chains onto polymers for applications requiring water repellency.
• Crosslinking Agent: Its structure can facilitate crosslinking in polymer networks, increasing thermal and chemical resistance.
• Chemical Intermediate: Utilized in organic synthesis to build more complex molecules for pharmaceutical or agrochemical research.

Quality Control

Our 3-Methylbuten-2-Yl Methacrylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay by GC or HPLC, identity confirmation (IR), and impurity profiling, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and polymerization risk. Keep away from heat, sparks, and open flames. Due to its highly volatile nature, ensure containers are kept upright and sealed when not in use. For long-term storage, consider under an inert atmosphere such as nitrogen.
