CarbonWrap® Putty W two-component epoxy putty — for work at +5…+23 °C

Composite strengthening

For work at low temperatures the CarbonWrap system provides Putty W, which is applied at air temperatures from +5 to +23 °C. It is used to level and prepare the surface before priming or installing the external reinforcement system, to repair small defects and cracks and to install carbon rods — on horizontal, vertical and overhead surfaces. The component ratio is 100:25 by weight, the pot life at 20 °C at least 50 min, and the bond to concrete exceeds 2.5 MPa.

Specifications

ManufacturerCarbonWrap — OOO “Nanotekhnologicheskiy tsentr kompozitov”, Moscow
Typecomposite strengthening
Basetwo-component epoxy putty paste: component A — thixotropic blend of epoxy resins, reactive diluents, fillers, pigments and functional additives; component B — polyamine hardener with filler and special additives; solvent-free
Colourcomponent A — grey; component B — white; mix — grey
Packagingcomponent A — 24 kg pails, component B — 6 kg pails
Application methodlevelling and surface preparation before priming or installing the external reinforcement system, repair of small defects, crack repair, installation of carbon rods (composite rebar); for horizontal, vertical and overhead surfaces; no separate primer required; A:B = 100:25 by weight; mixing with a low-speed mixer at 300–400 rpm with a paddle for 3 min, especially at the bottom and walls, until uniformly grey, then 1 min at low speed to reduce air entrainment; applied with a spatula
