Description

Isobutyl Methacrylate CAS NO 97-86-9 is a monofunctional methacrylate ester monomer characterized by its highly volatile nature and a reactive double bond. This compound is a crucial building block in the synthesis of polymers and copolymers, offering excellent weatherability, low-temperature flexibility, and hydrolytic stability to the final materials. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for the production of acrylic resins, impact modifiers, and specialty polymers.

Application

• Manufacturing of solvent-based and water-based acrylic resins for industrial and automotive coatings.
• Production of pressure-sensitive and structural adhesives, as well as sealants.
• Synthesis of impact modifiers and processing aids for engineering plastics like PVC.
• Key monomer for UV-curable resins and inks used in graphic arts and 3D printing.
• Component in the production of acrylic elastomers and rubber modifiers.
• Used as a reactive diluent and crosslinking agent in various polymer systems.
• Intermediate in the synthesis of specialty chemicals and pharmaceutical agents.

Quality Control

Our Isobutyl Methacrylate is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, inhibitor content, and impurity profiles 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. Recommended storage temperature is between 15°C and 25°C. Due to its highly volatile and polymerizable nature, containers should be kept tightly sealed and under an inert atmosphere after opening to maintain quality and prevent premature polymerization.
