Description

Allyl Crotonate is an unsaturated ester monomer characterized by its reactive allyl and acrylate functionalities. This compound matters as a versatile chemical intermediate, enabling the synthesis of specialty polymers and fine chemicals through its dual reactivity. It is needed by manufacturers in the polymer, coatings, and adhesive industries seeking to introduce cross-linking sites or modify material properties.

Application

• Polymer & Resin Modification: Used as a co-monomer to introduce cross-linkable allyl groups into acrylic and vinyl polymers, enhancing thermal and chemical resistance.
• Specialty Coatings & Inks: Serves as a reactive diluent and building block in UV-curable and high-performance coating formulations.
• Adhesive & Sealant Production: Imparts improved adhesion and flexibility when incorporated into acrylic-based adhesive systems.
• Chemical Synthesis: Acts as a key intermediate in organic synthesis, particularly in Diels-Alder reactions and the production of flavor and fragrance compounds.
• Surface Treatment Agents: Utilized in the manufacture of surface modifiers and primers for plastics and metals.

Quality Control

Our Allyl Crotonate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets precise specifications. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance and regulatory needs.

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 for extended stability.
