CarbonWrap® Putty W two-component epoxy putty — for work at +5…+23 °C
Epoxy putty for preparing the substrate for CarbonWrap at low temperatures, from +5 to +23 °C; suitable for overhead surfaces.

CarbonWrap Resin 530+ saturating resin is intended for carbon reinforcing materials with an increased areal weight: tapes and fabrics are impregnated with it by the “wet” method by hand or mechanically, with impregnating machines. The resin also serves as the primer resin, is mixed at a ratio of 100:30 by weight and gives a bond to concrete of more than 2.5 MPa and a shear strength of at least 12 MPa. The standard version is applied at +15 to +35 °C and cures in 7 days, the “winter” version at +10 to +35 °C and in 5 days, so the version is specified when ordering.
