1. Acetate/n-butyl content ≥99.8%, effectively reducing the impact of impurities on resin, ink, and adhesive systems.
2. Acetate/n-butyl CAS 123 86 4 moisture content ≤0.05%, reducing the risk of coating whitening.
3. n-Butyl Acetate Solvents acid value controlled ≤0.005% (based on acetic acid), reducing the impact of acidic impurities on production equipment and reaction systems.
For packaging printing, coating, and adhesive companies, the evaporation rate and impurity content of n-Butyl Acetate Solvents directly affect the application effect. Problems such as inconsistent drying speed, ink residue, coating whitening, and decreased adhesion are likely to happen if Butyl Acetate C6H12O2 purity is inadequate, moisture content is too high, or acid value changes significantly during high-speed printing and spraying. That will eventually result in product reworked, the line being shutdown for fine-tuning, and the production cost going up. We supply ethyl acetate conforming to GB/T 3728-2021 standards, with a purity ≥99.8%, moisture ≤0.05%, and acid value ≤0.005%, and strictly control color and evaporation residue. A Stable product evaporation rate and solubility characteristics are of great benefits; the user can not only minimize the formulation changes needed but also achieve high print and coating quality consistency as well as shorter process adjustment time, for the most part, by about 20%. First-pass yields are likely to go up at the same time and a production loss due to raw material variation will definitely drop down.

Upstream Laboratories and Technical Support
Acetate n butyl is widely used in packaging printing, automotive coatings, adhesives, electronic cleaning, pharmaceuticals, and fine chemicals industries. Properties such as its purity, moisture level, acid value, and evaporation residue significantly influence factors such as solubility, evaporation speed, and the quality of the final product. With the support of upstream cooperative production bases and CNAS accredited labs, we've implemented a complete system for testing and ensuring the quality of our products. The laboratory is equipped with over 30 analytical instruments, including a gas chromatograph (GC), GC-MS, Karl Fischer moisture analyzer, automatic potentiometric titrator, and colorimeter, enabling precise detection of product purity, moisture content, acid value, color, evaporation residue, and trace impurities. For printing inks and coatings we also do a special check of ethyl acetate's evaporation rate and compatibility with solvents, solubility in which all together will give us a consistent performance with different batches.
Customer Case Study
A South American packaging and printing company has long produced flexible packaging inks for food packaging. Previously, the ethyl acetate they used exhibited significant fluctuations in moisture content and evaporation rate, leading to uneven drying and high residual solvent levels during high-speed printing, resulting in rework of some products. Once the client integrated our ethyl acetate which possesses ≥99.8% purity, ≤0.05% moisture content, and stable volatility, the results he received were that his ink dissolution has become more stable, printing has dried a bit earlier by about 15%, the time required for changing setup on the production line has been cut by 30%, and he has increased his first-pass yield (i.e., a product passes the quality control with no defects on the first attempt) by 10%, thus resulting in his production costs getting lower overall.
