Recommended Usage

Add the product directly to the foaming system to ensure that it is evenly dispersed. If dilution is required, it is best not to store the diluents for more than 24 hours

For the higher foaming temperature (> 60 ℃), it is suggested that the RJ-O106TH should be added to the system before 60 ℃ to disperse evenly, so as to give full play to its maximum effect..

According to the factors such as viscosity, temperature and agitation of different foaming systems, 10ppm is selected as the unit to select more economical dosage. Generally speaking, the dosage of 30-200ppm can guarantee the ideal defoaming effect. Some industries, such as biological fermentation, may need 2-5 per thousand.


RJ-O106T is available in 25kg, 50kgs , 200kg plastic drum and other packing on request.
