Agrochemical suspension concentrates and aqueous formulations, plus other source-listed aqueous systems.
The following functions are described in the published source; they are not measured results for every formulation.
The source describes foam prevention, control and removal in aqueous systems, with ready dispersion in water.
See the technical specifications table above and the source TDS below. Keep the stated units, dosage basis and test conditions together when comparing grades.
The emulsion may be added directly to the foaming system or added after dilution with water. The data sheet does not state a numerical dosage, dilution ratio, mixing speed or addition stage; ask our technical team for a starting level and the basis it is calculated on.
Store between 2 and 35 °C. Shelf life is 12 months from the date of manufacture.

The linked document identifies its issuer, brand and model. A catalogue listing does not by itself establish the manufacturer or a brand authorization. Confirm the manufacturer and any applicable authorization for the exact grade when requesting a quotation. A TDS is not a substitute for a separate SDS.
Send the formulation type, active ingredient, pH and the process stage where foam appears to our technical team, and we will confirm the starting dosage, suitable addition point and a sample for testing in your own system.
