Freshly applied facade paints have long drying times and are therefore more susceptible to water and dirt. With the new additive TEGO Guard 9000 from Evonik Coating Additives it is possible to protect building and house facades as soon as they are applied. TEGO Guard 9000 improves the stabilization of the paint components in facade paints, so that the paint is quickly protected against the effects of weathering. In addition, the additive can be used universally: regardless of the selected binder, the PVC and the selected color. TEGO Guard 9000 is suitable for water-based and therefore environmentally friendly facade paints.
While conventional exterior wall paints with a high pigment volume concentration (PVC) take around three hours or longer to dry, the new TEGO Guard technology enables high rain resistance just a few minutes after painting. The electrostatic interaction between a cationic organic polymer and the anionic color components in thecolor formulation are responsible for this.
