Description

tert-Butyl Methacrylate is a high-purity, highly volatile monomer essential for the synthesis of advanced polymers. Its unique sterically hindered tert-butyl group imparts exceptional properties to resulting copolymers, such as enhanced thermal stability, chemical resistance, and tailored glass transition temperatures. This makes it a critical raw material for manufacturers in the coatings, adhesives, and specialty plastics industries seeking to engineer high-performance materials.

Application

• Acrylic Resin Modifier: Key monomer for producing specialty acrylic and methacrylic copolymers with improved heat resistance and solubility parameters.
• High-Performance Coatings: Used in automotive, industrial, and architectural coatings to enhance durability, gloss retention, and weatherability.
• Adhesive & Sealant Formulations: Imparts flexibility, adhesion, and environmental resistance to pressure-sensitive adhesives and structural sealants.
• Optical Polymers: Serves as a co-monomer in the production of optical lenses and transparent plastics with precise refractive indices.
• Lithographic Materials: Used in photoresists and printing plates for the electronics and printing industries due to its reactive methacrylate group.
• Dental & Biomedical Materials: A component in dental composites and bone cements where biocompatibility and controlled polymerization are required.
• Hydrophobic Polymer Additive: Incorporated into polymers to increase hydrophobicity and reduce surface energy for water-repellent applications.

Quality Control

Our tert-Butyl Methacrylate is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets exacting specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, guaranteeing traceability and compliance with 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 acids, bases, and oxidizing agents. Due to its highly volatile nature, keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C (refrigerated) to maximize shelf life and inhibit premature polymerization.
