Yes. The IFT Institute, based in Rossenheim, Germany, has fully approved the products, after developing an evaluation and investigation program based on the durability and sustainability of the products that have been used to treat windows and frames. The results of this test are that the products of Repair Care International are 'ideal for practical use'.
In addition to this, Repair Care International has had a test station in the Austrian Alps, (near Bregenz) for over 10 years, where the products are exposed to extreme weather conditions.
All the testing institutes across Europe have collectively agreed on the test results.
