Silicone-Based Defoamer SD40 – For Industrial & Wastewater Foam Control
We offer Silicone Defoamer SD40, in Gujarat and all over India, These Silicone Defoamer is highly efficient, long-lasting defoaming agent used in Effluent Treatment Plants (ETP), Sewage Treatment Plants (STP), and various industrial processes to control and eliminate unwanted foam formation.
Green Tech SD-40 is a new breakthrough in the dyes, chemicals, intermediates and influent plants where foaming are accruing during process or reaction. At the time of foaming, it should be speedily controlled or may be nullified. In earlier days people are using solvents but it has so many drawbacks. Now-a-days modified silicon defoamers are normally preferred due to better stability, better lasting de foaming and antifoaming power. Modified silicon defoamer involved fine particle size and selected emulsifying agent imparting ability to with stand both over emulsification and agglomeration.
