Overview of KEIM Mycal®-System Products

KEIM Mycal®-Top

KEIM Mycal-Top is a highly specialised interior silicate paint with different effect approaches against mould contamination. The enormous diffusion potential and the humidity-regulating properties provide dry walls. It creates an alkali depot and thus demonstrably does not offer a nutrient base to mould. Photocatalytically active pigments are able to decompose pollutants.
