Low Odor Slow Evaporation EEP Ester Solvent CAS 763-69-9 for Coatings Inks

Ethyl 3-Ethoxypropionate, commonly abbreviated as EEP, is a colorless ester solvent characterized by a mild ester odor, relatively slow evaporation, good solvency, and useful compatibility across many coating formulations. Its chemical name is Ethyl 3-Ethoxypropionate, and its CAS number is 763-69-9.

EEP is particularly suitable where controlled evaporation and good film formation are required. It can be used in industrial coatings, printing inks, paints, resin systems, electronic chemicals, cleaning formulations, and other specialty solvent applications.

Actual specifications may vary by production grade and batch. Please refer to the corresponding COA before use.

Ethyl 3-Ethoxypropionate is an ester solvent combining an group and an ester group within the same molecule. This molecular structure gives EEP useful solvency toward a variety of coating resins while maintaining a relatively slow evaporation profile.

Compared with many faster-evaporating solvents, EEP can extend open time during coating application. This property may support better leveling, smoother film formation, reduced surface defects, and more controlled solvent release during drying.

The product is a clear liquid under normal conditions. Its boiling point is approximately 166°C, while its flash point is approximately 58°C. It is classified as a flammable liquid and should be handled according to the applicable SDS and local chemical safety requirements.

• Slow and controlled evaporation rate

• Good solvency across various resin systems

• Mild ester-type odor

• Good flow and leveling characteristics

• Suitable for coating formulation adjustment

• Useful as a high-boiling organic solvent

• Compatible with many industrial solvent blends

• Suitable for precision formulation applications

EEP can be used as a slow-evaporating solvent in industrial coating systems. Its evaporation profile helps maintain coating fluidity during application and may improve leveling before the film completely dries.

It is applicable to selected automotive coatings, metal coatings, wood coatings, protective coatings, and other industrial finishing formulations.

Ethyl 3-Ethoxypropionate can be incorporated into certain printing ink systems where controlled drying and stable viscosity are required. Its solvent characteristics can assist resin dissolution and formulation consistency.

EEP may be used as a co-solvent in paint formulations to regulate evaporation speed, improve flow, and support smoother film formation.

Its solvency makes EEP suitable for selected synthetic resin formulations. It can function as a carrier solvent or formulation solvent depending on resin type, concentration, and processing requirements.

EEP is also used in selected electronic chemical formulations where controlled evaporation, cleanliness, and solvent performance are important.

Its organic solvency allows use in selected industrial cleaning formulations designed to remove oils, resins, coating residues, and other organic contaminants.

One of the main advantages of Ethyl 3-Ethoxypropionate is its relatively slow evaporation rate.

During coating application, a solvent that evaporates too quickly may cause poor leveling, uneven surfaces, or premature film formation. EEP remains in the wet film longer, allowing additional time for resin flow and surface leveling.

This makes it useful as part of a balanced solvent blend, especially when formulators need to adjust drying behavior without relying solely on very fast solvents.

• Maintain appropriate application viscosity

• Extend wet-film open time

• Improve coating flow

• Support surface leveling

• Reduce excessively rapid solvent loss

• Improve formulation stability

• Adjust overall solvent blend evaporation

• Steel drums

• IBC containers

• ISO tanks

• Bulk shipment

Store Ethyl 3-Ethoxypropionate in a cool, dry, and well-ventilated area. Keep containers tightly closed when not in use.

The material should be kept away from heat, sparks, open flames, hot surfaces, and incompatible materials. Suitable grounding and bonding procedures should be followed during bulk liquid transfer where required.

Always consult the current Safety Data Sheet before storage, transportation, or industrial use.
