                                    Agricultural Silicone Surfactant & Silicone Adjuvant

TOP WIN can produce various silicone adjuvants with similar performance as Silwet 408, Break Thru S240, Dow Corning Q2-5211, Silwet L-77, Silwet 806, and so on.

Other descriptions: Agricultural Organic Silicone Synergistic Agent, Organo Silicone Surfactant , Agricultural Silicone Surfactant , Agricultural Spreading and Penetrating Agent, Spray Adjuvant for Agricultural Applications, Silicone Adjuvant for Agricultural, Agricultural Silicone Spreading and Penetrating Agent, Silicone Spreader for Agricutural, Polyether Modified Trisiloxane for Agricultrual, Organosilicon Pesticide Synergist Surfactant, Silicone Super Wetting Spreading Agent, Organosilicon Super Penetrating Spreading Surfactant. 

Performance: TOP WIN’s Silicone Spray Adjuvant reduces the surface tension of aqueous agricultural mixtures significantly lower than conventional nonionic surfactants. At concentrations as low as 0.01 percent, it reduces surface tension below 23 dynes/cm, which produces very rapid wetting and spreading on hard-to-wet surfaces such as waxy leaves.

In addition to the rapid wetting and spreading, Silicone Surfactant also greatly increases the uptake of chemicals into plant tissues. Adding the Silicone Surfactant to a herbicide tank-mix may significantly enhance its efficacy, particularly in the control of broadleaf weeds with water-soluble herbicides. The rapid uptake produces “rainfastness”; i.e., herbicides are not washed off by rainfall because they have penetrated the plant surface.
