Description

Isopentyl 2-Ethylacrylate CAS NO 67634-18-8 is a specialized acrylate ester monomer valued for its unique combination of a branched alkyl chain and an ethyl-substituted acrylate group. This structure is critical for imparting specific performance characteristics, such as enhanced flexibility, hydrophobicity, and low-temperature properties, to polymer formulations. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and specialty polymer industries for developing advanced materials with tailored performance profiles.

Application

• UV-Curable Coatings and Inks: Serves as a reactive diluent and cross-linking agent to improve flexibility, adhesion, and weather resistance in radiation-curable systems.
• Pressure-Sensitive Adhesives (PSAs): Used to modify acrylic copolymer formulations, enhancing tack, peel strength, and low-temperature performance.
• Acrylic Resin Modification: Incorporated as a co-monomer to impart internal plasticization, reducing brittleness and improving impact resistance in acrylic polymers.
• Specialty Elastomers and Sealants: Contributes to the synthesis of polymers with low glass transition temperatures (Tg) for flexible, durable seals and elastomeric components.
• Fiber and Textile Finishing Agents: Utilized in polymers applied as softeners, water repellents, or durable press finishes.
• Lubricant and Fuel Additive Intermediates: Acts as a chemical building block for synthesizing esters used as viscosity modifiers or pour point depressants.

Quality Control

Our Isopentyl 2-Ethylacrylate is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure it meets precise purity and composition specifications. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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.
