Tests regarding pigmented construction materials’ resistance to bad weather.

Buildings are expected to stand the test of time. Therefore, an essential criterion for the selection of proper pigments for construction materials is their resistance to bad weather and to light.

But how can this resistance to chronological time be shown if its proof depends on the actual exposure to bad weather for an actual period of time?

One way of doing this is to perform external tests for the period of time required to answer to issues regarding resistance and stability.  

This need was recognized many years ago by Bayer, the company that originated LANXESS. This is why tests with pigmented materials are performed since 1960 in several “Exposure to Bad Weather Stations” in Germany and other countries, where equipment has been installed to manufacture products under standard industrial conditions, proper spaces organized to exposure such products to bad weather for long periods of time and technology developed to ensure data documentations.

In Brazil, in order to fulfill the growing market demands, LANXESS opened its Application Field, where application tests of products from the Bayferrox® and Xadrez® lines are performed. The project also includes a showroom, where it is possible to exhibit customers’ products which employ pigments in their production, as well as to perform assessment regarding bad weather conditions and the effects of chemical products.
