Description

Butyl Crotonate is a versatile ester monomer widely used in polymerization and specialty chemical synthesis. Its value lies in its ability to introduce specific functional groups and modify polymer properties, making it a key intermediate for advanced materials. This product is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to develop products with tailored performance characteristics.

Application

• Polymer & Resin Modification: Acts as a reactive monomer or co-monomer in the production of acrylic and vinyl polymers to adjust flexibility, adhesion, and glass transition temperature (Tg).
• Specialty Coatings & Inks: Used in the formulation of high-performance industrial coatings, printing inks, and overprint varnishes to enhance film properties and durability.
• Adhesive & Sealant Formulation: Serves as a building block for pressure-sensitive adhesives (PSAs) and elastomers, improving tack and cohesive strength.
• Chemical Intermediate: A valuable precursor in organic synthesis for pharmaceuticals, agrochemicals, and flavor & fragrance compounds.
• Plasticizer & Additive Production: Employed in the manufacture of specialty plasticizers and additives for polymers like PVC.
• Crosslinking Agent: Functions in radiation-curable systems and thermosetting resins to create crosslinked polymer networks.

Quality Control

Our Butyl Crotonate is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, purity, and impurity profile analysis, to meet exacting industrial and technical grade specifications. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment 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 incompatible materials such as strong bases 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 maintain product integrity.
