is designed to increase the fire resistance of steel load-bearing structures in normal indoor and outdoor environments. The effect of fire, i. under the influence of heat, this one-component water-based coating foames, thereby forming an insulating layer on the surface of the treated steel structure that will prevent this construction from overheating to a critical temperature and for a specified (desired) time. It has a high content of non-volatile substances. Thanks to the water-based base, hazardous vapors (as with solvent-based coatings) do not arise, which is a great advantage when used in closed areas and also allows work in explosive atmospheres. Since it is not a hazardous material, its transportation and storage is also more advantageous than that of solvent coatings.
Polylack W can be stored and applied only at ambient and substrate temperatures from +5 to 35 ° C.
Thinning: It is not necessary to dilute with water if necessary max. 3%
Drying at 23 ° C and 250 micron thickness: dustproof after 1 hour, touch-resistant after 24 hours, overcoatable after 8 hours, topcoatable after 24 hours”
