A WP is a powder formulation that forms a suspension when mixed with water prior to spraying.
WP formulations consist of one or more active ingredients which are blended and mixed with inerts, diluents and surfactants.
Wetting agents are used to facilitate the suspension of the particles in water. A dispersing agent is added to prevent any flocculation of the suspension before it is applied.
The wetting agent aids in the incorporation of the wettable powder into the water phase at the time of dilution and functions at the solid/liquid interface. Wetting agents reduce the surface tension between the solid powder surface and the water surface, with the result that the powder wets and mixes with the water in the spray tank more easily.
Once the powder has been diluted in water and is ready for spraying (with the aid of the wetting agent), a dispersant is required to maintain the particles in suspension and prevent them from agglomerating.
The Dispersol™ range are blended products with both dispersing and wetting properties. Please contact us to discuss if this range is available in your region.
