Ethyl 3-ethoxypropionate
Acronym: EEP
CAS NO.: 763-69-9
Ethyl 3-ethoxypropionate (EEP solvent) is a low volatile ether ester with good solubility for a wide range of coating polymers. The ether ester group, linear structure, and propionyl group in the center of the molecule give this material a combination of properties not found in other solvents: slow volatility, low susceptibility to solvent cracking in baking applications, high solubility in a wide range of polymers, low solution viscosity (relative to its evaporation rate), good solvent release from the coating film, and good flow and leveling properties in a wide range of coatings. EEP solvent has low odor, low surface tension, high resistivity. It has special color-fixing functions such as preventing silver powder from returning to roughness, blackening and yellowing. It has unique effect in the field of color fixing of automobile paint and car refinishing paint. It can be used in microelectronics and LCD industry to make photoresist as residue-free cleaning agent.
