Profskrin RC470 — R4 repair mortar for structures of class B50 and above
Thixotropic R4 mortar for repairing high-strength concrete and reinforced concrete of B50 and above; 70 MPa at 28 days, water impermeability W20.

FE851 AS is the conductive layer of an antistatic system: the black epoxy primer with a conductive additive is applied over a levelled, primed epoxy surface before the finishing coat. The electrical resistance of the layer is 10³–10⁵ Ω, adhesion to concrete is at least 2.5 MPa, and the fire hazard class is KM2. It is used at electronics, aviation, chemical and oil-refining facilities, in medicine, cleanrooms, data centres and laboratories.
