Evonik
Evonik's TEGOVAPRO technology delivers exterior shine for coatings that are water repellent from the outside but permeable to water vapor from the inside.
Glossy coatings are usually used on the outside that repel water but are not permeable, so when water vapor presses against the coating on the inside, it produces cracks and bubbles.
This innovation simply replaces a part of the primary binder, giving the formulation a new property without the need for additional expense.
The technology makes it possible to formulate high-quality exterior coatings ranging from semi-matte to high gloss.
For exterior matte coatings that are permeable but not water repellent, Evonik offers TEGO Phobe, an additive that lends hydrophobic properties to the coating, making it water resistant without impacting permeability.
