TESSO DF-50 Cement Defoamer
TESSO DF-50 is a non silicone defoamer designed to provide maximum foam control in cement slurry. Besides preventing foam forming, the product also has a good foam killing effect on both surface and entrapped foam and is compatible with most cement additives.
TESSO DF-50 is usually used undiluted, the most effective way of using the product is to add the product at a position where an adequate mixing is possible.
For killing the already formed foam, TESSO DF-50 can also be diluted in water and sprayed over the foam or circulated together with the foaming fluids.
In general a dosage of 0.01 – 0.05 gallon TESSO DF-50 per sack cement will be sufficient to obtain a good foam control.
