ALFAPOL PU-4VN(i) — non-sparking highly filled polyurethane-cement floor
Highly filled non-sparking polyurethane-cement floor for fire-hazardous production facilities, storage facilities and outdoor areas.

The PU-1G kit includes two components and graded quartz filler: without the filler the compound works as a primer, with it as a putty. The primer strengthens the substrate and improves chemical resistance; it is vapour-permeable and solvent-free. Bond strength to concrete is at least 2 MPa, and the next layer is applied no earlier than 12 hours later at +20 °C.
