Agricultural Solutions


If plant protection products are applied, it is important that they produce an optimum effect to secure maximum protection.
Substrate wetting agents of the CHT Group can highly contribute to this. They excellently decrease the interfacial tension between a solid substrate and a liquid.

The modified silicones in use (silicone polyethers) are water-soluble up to water-dispersible and have a distinct surface activity. Through the targeted adjustment of the ratio between hydrophilic and hydrophobic structural units we are able to provide you with specifically efficient wetting agents for aqueous and solvent-based systems. The addition of these additives results in an outstanding distribution of the plant protection products on the desired substrate.

Foam can clearly reduce the efficiency of aqueous agricultural formulations. Defoamer compounds, emulsions or fluids on silicone base can be used for foam inhibiting. Highly efficient defoamers which show the desired performance even under adverse conditions such as low pH values or high electrolyte contents can be produced through the special modification of the silicones.

Substrate wetting agents

Substrate wetting agents decrease the interfacial tension between substrate and a liquid. Polyether siloxanes are very efficient and are mainly added in lowest concentrations to aqueous coating systems.
