Applications:
It is a type of low viscosity silicone polyether copolymer liquid used to enhance the performance of wetting, spreading and penetration of agricultural chemicals. It may be used as a formulation ingredient in water-soluble broadleaf herbicides and insecticides, fungicides and plant growth regulators, or as a tank-mix adjuvant for foliar-applied chemicals.
Performances:
Perfecto MC series silicone surfactant reduces the surface tension of aqueous agricultural mixtures significantly lower than is achievable with 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, Perfecto MC series 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 into the plant surface.
How to Use in Agricultural Chemical Formulations:
Perfecto MC series silicone surfactant may be used as an ingredient in formulations, provided that all the ingredients are compatible. The silicone surfactant is stable in pH=6-8 aqueous formulations, but will degrade rapidly in strong acidic or strong alkaline formulations. New product formulations should be thoroughly tested for performance and shelf stability before entering market.
As an Agricultural Chemical Tank-Mix Adjuvant:
Perfecto MC series silicone surfactant may be added to tank-mixes to enhance the biological performance of the spray solution.
