Product Introduction

A colorless, transparent, low‑toxicity, environmentally friendly ether‑ester solvent with a mild ester‑like odor.
It offers a moderate evaporation rate, significantly improving film leveling and reducing pinholes.
Due to its low toxicity and high flash point, it is widely used in high‑end coatings, electronic photoresists, industrial cleaning, and ink applications.
Molecular formula: C₆H₁₂O₃
CAS No.: 108‑65‑6

Features

Environmentally friendly, low toxicity, strong regulatory compliance：As a low‑toxicity ether‑ester solvent, it has no reproductive toxicity, emits low VOCs, and can replace highly toxic solvents such as toluene, xylene, and glycol ethers – complying with REACH and other environmental regulations.
Broad solvency and excellent compatibility: Its molecular structure combines both polar and non‑polar characteristics, providing strong dissolving power for various polymers such as acrylics, epoxies, polyurethanes, and nitrocellulose resins. It is miscible with most organic solvents and can also be used as a co‑solvent in water‑based systems.
Balanced evaporation rate and superior film formation: It is a slow‑evaporating solvent, helping to avoid defects such as pinholes, orange peel, and blushing during application. It effectively improves coating leveling, surface gloss, and film density – suitable for thick coatings, precision coating, printing, and similar processes.
