Ethyl 3-Ethoxypropionate (EEP), identified by CAS number 763-69-9, is a high-performance, slow-evaporating ether-ester solvent characterized by its linear molecular structure. It is increasingly fa…
Controlled Evaporation: The slow evaporation rate ensures superior film formation, preventing surface defects like “solvent pop” or “orange peel” in high-gloss coatings.
High Solvency Power: Effectively reduces the viscosity of high-solids resin systems, allowing for lower VOC formulations without compromising performance.
Low Surface Tension: Promotes excellent substrate wetting and pigment stabilization, which enhances adhesion and color uniformity.
Safety Profile: Offers a mild odor and low acute toxicity; it is non-HAP and is not listed under SARA Title III, Section 313.
Hydrolytic Stability: Exhibits high resistance to hydrolysis compared to other esters, ensuring shelf-life stability in various formulations.

技术亮点
Chemical Formula: C7H14O3 with a molecular weight of 146.18 g/mol.
Boiling Point: Approximately 170°C (338°F), contributing to its high-boiling characteristics and late-stage film integration.
Vapor Pressure: Extremely low at 0.7 mmHg at 20°C, which minimizes evaporative losses during the initial stages of application.
Flash Point: 58°C (136°F) via Closed Cup method, categorizing it as a combustible liquid for storage and transport.
Hansen Solubility Parameters: δd (15.5), δp (4.9), δh (6.6), indicating broad compatibility with polar and non-polar resin matrices.
Electrical Resistance: High electrical resistance, making it suitable for use in electrostatic spray applications.
