Description

2-Ethylhexyl Crotonate is a high-purity specialty ester monomer with the CAS registry number 45124-23-0. This compound is valued for its role as a reactive diluent and modifier in advanced polymer synthesis, offering excellent compatibility and performance characteristics. It is a critical raw material for manufacturers in the coatings, adhesives, and specialty plastics industries seeking to enhance product flexibility, adhesion, and durability.

Application

• Reactive Diluent in UV-Curable Coatings and Inks: Used to reduce viscosity without compromising the final film properties, improving application and cure speed.
• Co-monomer for Acrylic and Vinyl Polymers: Imparts internal plasticization, enhancing the flexibility, low-temperature performance, and adhesion of polymer films.
• Modifier for Pressure-Sensitive Adhesives (PSAs): Adjusts tack, peel strength, and shear resistance in adhesive formulations.
• Intermediate for Specialty Chemical Synthesis: Serves as a building block for producing other esters, plasticizers, and surface-active agents.
• Additive for Sealants and Caulks: Improves workability, elongation, and long-term weatherability of elastomeric formulations.
