IZOLEP-pro — penetrating epoxy primer for concrete
Colourless penetrating epoxy primer for concrete of bridges and structures: it strengthens the surface and serves as a base under epoxy enamels.

A high-build fast-drying primer-enamel on a modified epoxy resin with an amine hardener; the anticorrosive pigment is zinc phosphate with an organic corrosion inhibitor. The material is particularly suitable for shop painting of steel structures: it is the primer coat under POLITON-UR (UV) and VINIKOR-62 enamels and PLAMCOR fire-retardant compounds, and in an open industrial atmosphere and indoors it is a stand-alone coating. It is applied at air temperatures from −10 °C, tolerates hand cleaning to St 2 and withstands +120 °C continuously in a dry atmosphere.
