Description

WynSpread® SW-255 Superwetting Spray Adjuvant for Agricultural Applications

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
  • Promotes rapid uptake of agrochemicals(rain fastness)
  • Reduces the residues of pesticides
  • Lowfoaming

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. 

Typical properties:
Appearance: Clear, light-yellow liquid
Viscosity(25°C):15-30 cs
Surface tension (0.1% aq/25°C.): £21.5mN/m

Performances:
SW-255 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, SW-255 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.

In addition to the rapid wetting and spreading, SW-255 Silicone Surfactant also greatly increases the uptake of chemicals into plant tissues. Adding SW-255 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:
SW-255 Silicone Surfactant may be used as an ingredient in formulations, provided all the ingredients are compatible. SW-255 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:
SW-255 Silicone Surfactant may be added to tank-mixes to enhance the biological performance of the spray solution.

Application 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%


Test a small area first to ensure that crop damage does not occur. Use the additive according to manufacturers’ label recommendation.

Usable Life and Storage:
When stored below 40°C (104°F), SW-255 Silicone Surfactant has a shelf life of 36 months from date of manufacture.

Packaging:
SW-255 Silicone Surfactant is available in 25 kg pails, 200 kg drums and 1000 kg tote-bins.
