For chemists, formulators, and technical buyers in the B2B chemical sector, a deep understanding of solvent properties is key to unlocking optimal product performance. Ethyl 3-Ethoxypropionate (EEP), identified by its CAS number 763-69-9, is an ether-ester solvent that offers a compelling technical profile. NINGBO INNO PHARMCHEM CO.,LTD., a specialist manufacturer and supplier, is your go-to source for this versatile chemical intermediate, providing detailed insights to aid your procurement decisions.

The technical advantage of EEP lies in its structure and resultant properties. As an ether-ester, it combines characteristics of both classes of solvents, offering excellent solvency for a broad range of polymers including acrylics, polyurethanes, and epoxies. This makes it a highly effective coalescing agent and flow modifier in coating systems, contributing to superior film formation and a smooth, defect-free finish. Purchasing EEP for your formulations means leveraging these inherent technical strengths.

One of EEP's most significant technical attributes is its slow evaporation rate, typically around 0.12 when compared to n-butyl acetate (ether = 1). This controlled volatility is critical in applications where extended working time is needed, such as in automotive coatings or high-solids industrial paints. It allows the coating to remain open longer, promoting better leveling and reducing the likelihood of surface defects like solvent popping or blushing. For technical procurement, buying EEP ensures enhanced application control.

Moreover, EEP boasts a high electrical resistance (20 Megohms), making it suitable for specialized applications in the electronics industry where dielectric properties are important. Its low surface tension (around 24.6 mN/m) aids in substrate wetting and penetration, crucial for both coatings and cleaning applications. The low water solubility (around 4.6% at 25°C) also provides formulation stability in certain systems.
