Isobutyl Methacrylate (IBMA), bearing the CAS number 97-86-9, is a prominent member of the methacrylate ester family, highly valued for its distinct chemical properties and versatile industrial applications. This clear, colorless liquid is a staple for chemical manufacturers and formulators seeking to impart specific performance characteristics to their products. Understanding its detailed properties is key for procurement managers and R&D scientists looking to optimize their material selections.

The chemical profile of IBMA is defined by its purity, typically a minimum of 99.5% as determined by GC analysis. This high level of purity is crucial, as impurities can significantly affect polymerization reactions and the final properties of the polymers derived from it. Additionally, IBMA boasts very low acid content (max. 0.01%) and moisture levels (max. 0.02%). These low impurity levels contribute to better storage stability and predictable reactivity, making it a reliable raw material for sensitive applications.

Physically, IBMA presents as a clear, colorless liquid with a molecular weight of 142.2 g/mol and a density of approximately 0.888 g/cm³ at 20°C. Its relatively low boiling point of around 155°C and a flash point of 43°C indicate its flammability, necessitating appropriate handling and storage precautions. These physical attributes are important considerations for logistics and industrial safety protocols when purchasing this chemical.

The primary utility of Isobutyl Methacrylate lies in its role as a monomer for acrylic resins. These resins are fundamental to a vast array of products. In the coatings industry, IBMA contributes to formulations that offer excellent weatherability, chemical resistance, and flexibility. This makes it indispensable for applications ranging from automotive finishes to industrial protective coatings. Manufacturers looking to buy high-performance coating ingredients will find IBMA to be a critical component.

In the adhesive sector, polymers incorporating IBMA exhibit strong bonding capabilities and good cohesive strength, coupled with the flexibility needed to accommodate substrate movement. This makes IBMA a preferred monomer for various adhesive formulations, including pressure-sensitive adhesives and structural adhesives. Procurement teams in the adhesive industry often seek reliable suppliers of IBMA to ensure product consistency.

Beyond these major applications, IBMA also finds its way into specialized areas such as dentistry materials, where its biocompatibility and mechanical properties are advantageous. It is used as a fiber treating compound, in paper coatings, and as an additive for lubricating oils, underscoring its broad industrial relevance.
