Silicone Surfactant Spray Adjuvant Silwet L-77

Key Features and Typical Benefits: • Nonionic • Superspreader for soluble liquid and emulsable concentrate formulations • Very low surface energy. • Rapid spreading and wetting. • Improve spray coverage • Super spreading and penetrating of spray agricultural chemicals • Promotes rapid uptake of agrochemicals(rain fastness) • Accord with enviromental protection,reduces enviromental pollution caused by pesticides • Reduces the residues of pesticides 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. Appearance: Clear, little yellow liquid Refractive index at 25°C: 1.440-1.450 Viscosity at 25°C (77°F): 30-50 cs Active Content percent: 100% Surface tension(0.1% aq.):£21.5 mN/m Performances: Silibase-2886 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, Silibase-2886 Silicone Surfactant reduces surface tension below 23 dynes/cm, which produces very rapid wetting and spreading on hard-to-wet surfaces such as waxy leaves. Thus, complete coverage can be achieved with herbicides, insecticides, fungicides and other agricultural chemicals. In addition to the rapid wetting and spreading, Silibase-2886 Silicone Surfactant also greatly increases the uptake of chemicals into plant tissues. Adding Silibase-2886 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: Silibase-2886 Silicone Surfactant may be used as an ingredient in formulations, provided all the ingredients are compatible. Silibase-2886 Silicone Surfactant is stable in neutral aqueous formulations (pH=6.5-7.5), but will degrade rapidly in acidic or alkaline formulations. New product formulations should be thoroughly tested for performance and shelf stability before entering market. As an Agricultural Chemical Tank-Mix Adjuvant: Silibase-2886 Silicone Surfactant may be added to tank-mixes to enhance the biological performance of the spray solution.
