Description

Crotyl Methacrylate is a specialized methacrylate ester monomer featuring a reactive crotyl group. This compound is valued for its ability to introduce internal unsaturation and specific reactivity into polymer chains, enabling the creation of materials with tailored properties. It is primarily sought by R&D chemists and formulators in the coatings, adhesives, and specialty polymer industries for developing advanced copolymers with enhanced cross-linking potential, adhesion, and chemical resistance.

Application

• Cross-linking Agent: Used to introduce reactive sites for subsequent curing or cross-linking in thermoset coatings and adhesives.
• Specialty Polymer Synthesis: A key monomer for producing copolymers with specific toughness, flexibility, and solvent resistance for industrial coatings.
• Adhesive Formulations: Enhances adhesion to low-surface-energy substrates like plastics and metals in structural and pressure-sensitive adhesives.
• UV-Curable Resins: Incorporated into oligomers and formulations for inks, coatings, and 3D printing resins that cure rapidly under UV light.
• Modifier for Acrylic Resins: Imparts internal plasticization and improves the low-temperature performance of acrylic polymers.
• Chemical Intermediate: Serves as a building block for synthesizing more complex chemical entities in pharmaceutical and agrochemical research.

Quality Control

Our Crotyl Methacrylate is manufactured under strict quality management protocols. Each batch is analyzed to ensure high purity and consistency, meeting the requirements for advanced chemical synthesis and polymer production. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). For long-term storage, consider blanketing with an inert gas such as nitrogen or argon to maintain product integrity. Keep away from heat, sparks, and open flame.
