Agrochemicals Organosilicone Silwet 408

  Post Date: Feb 02,2023
  Expiry Date: Aug 01,2023
  Detailed Description: Cas No. :104780-66-7;67674-67-3 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

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.

Typical product data
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

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.
Typical use rate
Plant growth regulators 0.03-0.05%
Herbicides 0.03-0.15%
Pesticides 0.03-0.1%
Fungicides 0.02-0.05%
Fertilizer and micronutrients 0.02-0.1%
Use the additive according to manufacturers' label recommendation.
Usable Life and Storage:
When stored below 40°C (104°F), Silibase-2886 Silicone Surfactant has a shelf life of 36 months from date of manufacture.
