Top Win WynSpread®SW-254
Super wetting Spray Adjuvant for Agricultural Applications
Key Features and Typical Benefits
Improve spray wetting and coverage
Super penetrating of spray agricultural chemicals
Promote rapid uptake of agrochemicals (rainfastness)
Hydrolysis resistance, suitable for the formulation with pH around 5.0-9.0
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.It is used in aqueous solutions.
Typical properties
Appearance: Clear, slight amber liquid
Viscosity(25C)：60-90cs
Cloudpoint(1.0%):45C
Surface tension(0.1%aq/25C):≤22.5mN/m
Performances
SW-254 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-254 Silicone Surfactant
reduces surface tension below 23dynes/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,SW-254 Silicone Surfactant also
greatly increases the uptake of chemicals in to plant tissues. Adding SW-254 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 was hed off by rainfall because they
have penetrated into the plant surface.
How to Use in Agricultural Chemical Formulations
SW-254 Silicone Surfactant maybe used as an ingredient in formulations,provided
all the ingredients are compatible.SW-254 organo silicon Surfactant are stable in
aqueous formulations(pH=6.0-9.0) and resistant to hydrolysis.New product
formulations should be thoroughly tested for performance and shelf stability before entering market.
As an Agricultural Chemical Tank-Mix Adjuvant
SW-254 Silicone Surfactant maybe added to tank-mixes to enhance the biological
performance of the spray solution.
Application Typical use rate
Plant growth regulators 0.03-0.05%
Herbicides0.03-0.15%

Fertilizer and micronutrients 0.02-0.1%
Use the additive according to manufacturers’ label recommendation.
Usable Life and Storage
When stored below40°C(104°F),SW-254 Silicone Surfactant has a shelf life of 36
months from date of manufacture.
