T80 silane impregnating agent comes as a thixotropic paste using n-octyltriethoxysilane, ideal for protecting vertical concrete from water and salts without dripping.
Summary Benefits at a Glance:
Penetration of 3-5mm in <C45 concrete for effective hydrophobic layer.
Lowers chloride absorption by more than 80% to resist corrosion.
Improves salt-freeze cycles by at least 15 over untreated surfaces.
Neutral pH and low odor make it easy to handle on site.
Product Introduction
T80 silane impregnating agent is formulated as a paste for precise application on vertical and overhead concrete. Powered by n-octyltriethoxysilane at 80% or higher, it diffuses into pores to build a hydrophobic structure that withstands water, salts, and alkalis. This breathable protection is key for tunnels, dams, and building facades where environmental stress is high. It maintains concrete's natural vapor flow, preventing issues like spalling, and offers extended durability in de-icing or marine areas.
Silane impregnating agent can be used for the protection of new concrete structures as well as for the reinforcement and repalof oldconcrete buildings, such as harbor wharves, cros-sea bridges, cross-river bridges, water conservancy project dams, urban elevated roads, highgrade highway bridges, railway bridges, tunnels, airpor pavements, exposed concrete buildings, thermal power plants,nuclear power plantssewage treatment plants, and so on.
They are particularly suitable for the protection of various concrete structuresthat are subject to seawatelcorrosion, salt fog corrosion, deicing agent corrosion, and freeze-thaw damage.

Product Usage
Remove loose materials and clean the surface with water or detergent, letting it dry fully. Spread T80 paste evenly with a trowel or brush, using 300-500 g/m² without dilution.
It sets initially in 2-4 hours and fully cures in 7 days.
Apply at 5-40°C, protecting from rain for 24 hours. Suited for vertical surfaces like tunnels, facades, and bridges to guard against water, salts, and weathering.
