DYNAWEED 260 E
ANTIFOAM EMULSION
DYNAWEED 260 E it’s a de-aerating and antifoam agent in water emulsion, formulated with modified polydimethylsiloxane that, because of its specific formulation, anyway avoids problems of adherence typical of classical antifoams made of standard dimethylpolysiloxane.
DYNAWEED 260 E resists in very acid and basic environments and maintains its antifoam characteristics also in systems where the temperature is very high.

APPLICATION:
DYNAWEED 260 E is used in many sectors, like textile field in dyeing machines, used as de-aerating agent in paints and varnishes, to manufacture detergents and surface tension modifiers.
In textile fields, generally the dosage is of 2-3 gr/l to be treated.
In paints and detergents, the dosage is from 0,2 to 0,7 % on the weight of preparation.
Correct dosage is set up anyway after preliminary trials and possibly changes according to the type of liquid to be treated.
