Hey'Di and Photocat A/S announced cooperation on selling stone impregnation in both the private and professional markets in Norway and Sweden. The ambition is to combine Hey'Di's long term experience of developing and selling surface treatments with Photocat's unique technology platform based on photocatalysis. Recently WHO announced, that air-quality limits need to be lowered significantly in order to save lives and increase quality of life for people living in cities with NOx-pollution.

Photocat has repeatedly documented that its solutions for treatment of existing surfaces can improve the air quality by reducing NOx in the environment. To meet these goals, usage of green technology is needed. Many steps are being taken across society; e.g. in development of cars, but it is important to realize that even if all cars eventually become electric; there would still be a need for additional measures to reach the WHO goals.
