TEGOPREN 5840 is a solvent free easy to handle liquid product. It shows excellent surface wetting properties in applications where difficult substrate coating is required. TEGOPREN 5840 reduces the surface tension of systems enhancing spreading on non-polar surfaces. It improves spreading and wetting properties. TEGOPREN 5840 is advisable in applications where negative interaction between substrates and coatings has to be overcome. TEGOPREN 5840 provides extraordinary reduction of surface tension in aqueous solutions and super spreading ability for fast coverage of large hydrophobic surfaces.
