The new coatings additive of Evonik ensures faster weather resistance and longer lasting protection of buildings and facades.
The
Coating Additives business line of Evonik
has recently presented TEGO® Guard 9000, a new additive that allows to protect building facades from the moment the paint is applied: while conventional high pigment-volume concentration (PVC) exterior facade coatings typically take three hours or more to dry, the new property of TEGO Guard 9000 offers an elevated rain resistance just a few minutes after the application.
“While the formulation requirements for exterior paints may differ around the world, the protection of buildings from environmental impact is universal. Coating formulators using TEGO® Guard 9000 can offer innovative and environmentally friendly facade coatings that can be applied more flexibly and regardless of weather conditions. Due to the increasing unpredictability of extreme weather caused by climate change and more stringent regulatory requirements, there is a growing demand for facade coatings that offer immediate weather resistance and long-lasting protection against environmental impacts,” has stated Katina Kiep, the head of the Decorative market segment of Evonik.
The new technology
promotes electrostatic interaction between a cationic organic polymer and the anionic paint ingredients in the coating formulation. The additive can be used universally – regardless of the binder, PVC and colour selected – and is suitable for environmentally friendly waterborne facade coatings. Additionally, the special formulation of TEGO Guard 9000 allows a personalised addition to formulations without affecting storage stability.
“The application of facade paints has been highly dependent on the weather, as newly applied facade coatings had traditionally long drying times, making them more vulnerable to water and dirt. Evonik’s new TEGO® Guard 9000 addresses this key customer pain-point by improving the stabilization of paint ingredients in facade coatings and providing almost immediate protection against weathering,” has added Ellen Reuter, the head of the Decorative market segment for the EMEA region of Evonik.
