KEIM Soldalit®-ME is a highly specialized, sol-silicate exterior paint with a photocatalytic action for organic, mineral and mixed substrates and on ETICS. Photocatalytically active, it reduces harmful gases (e.g. NOx, VOC's) and organic pollutants.
Facing the continuously growing traffic volume, clean breathing air becomes an ever more valuable commodity. But cities and communities struggle to achieve climate improvements. Up to now, traffic regulating measures have not really been successful.
Mineral facades can also work as a catalyst like ceramic in a catalytic converter. You only need KEIM Soldalit®-ME and light. This principle is called catalysis: A substance is stimulated by light to initiate a chemical reaction, without being consumed. This activates oxidation processes and organic substances and nitrogen oxides are decomposed. Thus, facades coated with KEIM Soldalit®-ME are able to promote the decomposition of air pollutants. Plus, the photocatalysis reduces the accumulation of spores.
Specific mineral pigments in KEIM Soldalit®-ME paint are responsible for this chemical process. To add those to common dispersion and silicone resin paints is difficult because their binding agent would become affected entailing sanding and a much-shortened longevity of the coating. KEIM Soldalit®-ME‘s photocatalytic effect was not only tested and proven in the laboratory but also through field trials.
Clean facades with environmental benefit
This photocatalytic effect can also decompose algae and organic dirt - another advantage besides the already excellent dirt resistance of silicate surfaces. A small commitment for the environment and an extra reward.
