JY-312 Metalworking Fluid Defoamer is presented by Juyou as a silicone-based defoamer for metal cutting fluid systems. Before a buyer approves repeat purchasing, the record should connect the actual cutting-fluid type, dilution condition, shear exposure, package choice and lot documents instead of treating all metalworking defoamers as interchangeable.
The current product source lists appearance as milky white liquid, viscosity at 25 C as 800-2000 mPa.s, ionic property as nonionic, active content as 100 percent, and water solubility as soluble in water. Treat these as supplier reference fields for the incoming material file, then request the TDS, safety document and certificate of analysis for the sample lot being evaluated.
Confirm dilution stability before line trials
Metalworking systems can differ sharply in oil content, emulsifier package, water hardness, pH, corrosion inhibitor and recirculation shear. A buyer should record whether JY-312 is being tested in a full-synthetic, semi-synthetic or emulsion cutting fluid, the dilution ratio, water source, mixing order, recirculation time and the foam measurement method. If the trial compares JY-312 with an existing defoamer, run both materials under the same dilution and shear conditions.
Do not approve a production order from a single beaker observation. Keep the supplier specification, the buyer’s diluted-fluid observation and the machine-side result as separate records. If foam improves but residue, separation or filtration behavior changes, the RFQ should stay in technical review until the compatibility question is closed.
Build the purchasing file around process evidence
- Incoming lot: product code, appearance, viscosity range, ionic property, active content, water solubility and COA version.
- Dilution record: cutting-fluid type, water quality, dilution ratio, addition point, mixing time and storage condition.
- Shear record: pump or circulation method, test duration, temperature and foam measurement timing.
- Commercial record: package request, destination, monthly consumption, delivery schedule and document requirements.
Ask Juyou for a controlled JY-312 sample package
Buyers should send the cutting-fluid chemistry, dilution ratio, current defoamer issue, circulation condition, package size, annual volume and required documents. Source product page: JY-312 Metalworking Fluid Defoamer.

Frequently Asked Questions
What should be checked first for JY-312?
Start with the cutting-fluid type, dilution ratio, water quality, mixing order and the TDS/COA that match the sample lot being tested.
Can one foam test approve the material?
No. Foam control, dilution stability, residue and filtration behavior should be checked under the buyer’s actual fluid and shear conditions.
Which package sizes are listed on the source page?
The source page lists 200 L plastic drum with 200 kg net weight and IBC tote with 1000 kg net weight.
What information belongs in the RFQ?
Include fluid type, dilution ratio, current defoamer problem, test method, package size, destination, expected volume and required documents.
