Description

Butyl Methacrylate CAS NO 97-88-1 is a versatile methacrylate ester monomer characterized by its long butyl chain, which imparts flexibility, hydrophobicity, and excellent weatherability to polymer systems. This compound is a critical building block in the synthesis of high-performance acrylic resins and copolymers. It is essential for manufacturers in the coatings, adhesives, plastics, and specialty chemical industries seeking to enhance product durability and processing characteristics.

Application

• Acrylic Resin Production: A key monomer for manufacturing solvent-based and waterborne acrylic resins used in industrial and automotive coatings.
• Adhesives and Sealants: Imparts flexibility, adhesion, and water resistance to pressure-sensitive adhesives (PSAs), structural adhesives, and caulks.
• Plastic Modifiers: Used as a co-monomer to modify the impact resistance, clarity, and processing of PMMA (plexiglass) and other engineering plastics.
• Textile and Leather Finishes: Employed in polymers for fabric coatings, leather finishes, and fiber treatments to improve softness and durability.
• UV-Curable Systems: Serves as a reactive diluent and crosslinker in inks, coatings, and 3D printing resins that cure under ultraviolet light.
• Oil Additives: Used in the synthesis of viscosity index improvers and pour point depressants for lubricating oils.

Quality Control

Our Butyl Methacrylate is produced under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and assay, to ensure it meets exacting industry specifications. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters are 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 acids and oxidizing agents. Recommended storage temperature is 15-25°C. The product typically contains an inhibitor (e.g., MEHQ) to prevent polymerization; storage conditions should be maintained to preserve inhibitor efficacy.
