Description

Isopropyl Methacrylate is a high-purity, monofunctional methacrylate monomer essential for advanced polymer synthesis. This compound is valued for its ability to impart specific properties like low-temperature flexibility, hydrophobicity, and enhanced weatherability to acrylic polymers and copolymers. It serves as a critical building block for industrial manufacturers in the coatings, adhesives, and specialty plastics sectors seeking to fine-tune material performance.

Application

• Acrylic Resin & Polymer Modification: A key monomer for synthesizing and modifying acrylic and methacrylic resins to improve flexibility and adhesion.
• UV-Curable Coatings & Inks: Used in formulations for wood, plastic, and metal coatings that require fast curing, high gloss, and chemical resistance.
• Pressure-Sensitive Adhesives (PSAs): Imparts tack and peel strength characteristics in adhesive tapes and labels.
• Fiber Optic Cladding: Employed in the production of specialty polymers for optical fibers due to its clarity and refractive index properties.
• Dental & Biomedical Materials: A precursor in the manufacture of biocompatible polymers for dental composites and medical devices.
• Automotive & Industrial Coatings: Enhances durability, weather resistance, and finish quality in automotive refinish and industrial maintenance paints.
• Reactive Diluent: Acts as a viscosity modifier and reactive solvent in unsaturated polyester and vinyl ester resin systems.

Quality Control

Our Isopropyl Methacrylate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizers and bases. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). The product typically contains an inhibitor (e.g., MEHQ) to prevent polymerization during storage; inhibitor content should be checked prior to use.
