Evonik has launched a new additive, TEGO^® Guard 9000, for protecting building façades from the environment. While conventional high pigment volume concentration (PVC) exterior façade coatings typically take three hours or more to dry, the new “Quick-Set property” of TEGO Guard 9000 technology enables high rain resistance just a few minutes after application. The technology promotes electrostatic interaction between a cationic organic polymer and the anionic paint ingredients in the coating formulation.

Additionally, the formulation of TEGO Guard 9000 allows for customized addition to formulations without affecting storage stability. The additive can be used universally, regardless of the binder, PVC and color selected, and is suitable for environmentally friendly waterborne façade coatings.
