APPLICATION
VINADEFOAM AF 150 has an excellent and lasting antifoam effect in pre-treatment process. Even with high-speed machines, a good anti-foam performance canbe obtained with small application amounts.
The product, pre-diluted with cold or warm water, can be added to the liquors but it is more economical to apply a sufficient amount at the very beginning of the procedure.
VINADEFOAM AF 150 is applied whenever foam develops in pre-treatment before introduction of any product in the process. The diluted product may also be sprayed at any time.
DILUTION
VINADEFOAM AF can be mixed in every ratio with cold and warm water. Nevertheless since the effectiveness of all silicone based anti-foaming agents depends on very fine dispersion it is advisable to dilute the product with cold water in a 1:9 ratio.
RECIPE PROPOSALS
We cannot recommend precisely a certain application amount since it depends on the foaming substance in the liquor, on turbulence and on air inlet. Normally the following amounts are recommended.
0.05 – 0.5 g/l VINADEFOAM AF 150
