Acrylic emulsion polymerization;

Dosage:

1.Can be added directly into the foaming system.Dosage is 0.1%-0.5%,or increase and decrease the dosage according to the foam quantity.

2.Can be added into the waterborned system after diluted 1-20 times with water.The effect will be more stable if diluted with the foaming liquid.

Note:

The foaming causes are various and complicated due to the different foaming media of various systems,although the product has a wide adaptability, it can not be applied to any kind of foaming system. Therefore, the user is requested to make a small sample experiment before defoaming.
