Fire resistance class up to EI 120.
mcr Polylack K is an intumescent mass in the form of dense putty The mass, after applying as a coat, or as a fill, creates a thermo-insulating foamy carbon layer on the surface heated to high temperature, which prevents burning of the polymer insulating coat at an early stage, and prevents propagation of flame along the protected surface.
The mass is used for filling in cavities, irregularities and gaps, as well as any other empty micro and macro-spaces occurring during fireproofing of installations, such as cables, cable trays and ladders, combined installation penetrations – as a supporting material – for filling and sealing. The mass is sold in 12.5 kg buckets, 600 ml foil containers and 310 ml tubes.
