Description

Methacrylic Acid (2-Hydroxyheptyl) Ester is a specialized methacrylate monomer featuring a long-chain hydroxyalkyl group. This unique structure is critical for imparting flexibility, adhesion, and hydrophobicity to polymer chains, making it a valuable building block for advanced materials. It is primarily sought by formulators and manufacturers in the coatings, adhesives, and specialty polymer industries seeking to enhance product performance.

Application

• UV-Curable Coatings and Inks: As a reactive diluent and crosslinker to improve flexibility, adhesion to low-energy surfaces, and chemical resistance.
• Adhesives and Sealants: To modify acrylic pressure-sensitive adhesives (PSAs) for enhanced tack, peel strength, and plasticizer resistance.
• Specialty Acrylic Resins: For synthesizing copolymers with tailored properties such as low-temperature flexibility and improved pigment wetting.
• Dental and Biomedical Materials: As a comonomer in formulations for dental composites and bone cements to modify mechanical properties and biocompatibility.
• Fiber Optic Coatings: To provide protective, flexible primary coatings with excellent environmental durability.
• Modifier for Rubber and Elastomers: To improve the processability and performance characteristics of various elastomeric compounds.

Quality Control

Our Methacrylic Acid (2-Hydroxyheptyl) Ester is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure it meets precise specifications and consistent performance for your formulations. Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F) under an inert atmosphere (e.g., nitrogen) to prevent oxidation and polymerization. Keep away from heat, sparks, and incompatible materials such as strong oxidizing agents and bases.
