Description

1-Methylbutyl Methacrylate is a specialized methacrylate ester monomer, valued for its unique branched alkyl chain which imparts specific performance characteristics to polymer formulations. This compound is essential for synthesizing high-performance acrylic polymers and copolymers with tailored properties. It is primarily utilized by manufacturers in the coatings, adhesives, and specialty plastics industries seeking to modify flexibility, hydrophobicity, and glass transition temperature.

Application

• Acrylic Resin Modification: Used as a co-monomer to adjust the glass transition temperature (Tg), flexibility, and solubility of acrylic polymers for coatings and adhesives.
• High-Performance Coatings: Imparts enhanced water resistance, weatherability, and adhesion in automotive, industrial, and architectural coating formulations.
• Pressure-Sensitive Adhesives (PSAs): Modifies tack, peel strength, and shear resistance in adhesive tapes and labels.
• Specialty Plastics and Acrylic Sheets: Incorporated to improve impact resistance and processing characteristics in cast or extruded acrylic products.
• UV-Curable Resins: Serves as a reactive diluent or functional monomer in inks, overprint varnishes, and 3D printing resins.
• Oil & Gas Additives: Potential use in the synthesis of polymers for drilling fluid additives or flow improvers.

Quality Control

Our 1-Methylbutyl Methacrylate is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by GC or HPLC, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We adhere to relevant industry standards and can support requirements for REACH and other global regulatory frameworks.

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 acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent moisture absorption and polymerization.
