AGITAN® SN 777 is an effective defoamer for aqueous systems and especially suitable for paper coatings as well as for natural and synthetic binders. It shows good antifoaming and foam breaking properties especially in coating colors for ink-jet papers. In these recipes the defoamer usually avoids surface defects on the layer of the coating and has good leveling properties.

Recommended levels/use

In coating colors AGITAN SN 777 is normally used in the level of 0,01 – 0,1 % calculated on the dry weight of the coating color. However it is recommended to adjust the dosage according to the situation of foam generated. The product should be tested on compatibility with the other used additives. AGITAN SN 777 is easily emulsifiable in water. The defoamer should be added undiluted in the beginning of the preparation of the coating color.
