T80A silane impregnating agent is a premium paste sealer featuring isooctyltriethoxysilane, providing targeted waterproofing for challenging concrete applications.
Summary Benefits at a Glance:
Diffuses 3-5mm into <C45 concrete for lasting hydrophobic matrix.
Decreases chloride ingress by over 80% to minimize damage.
Enhances freeze-thaw performance with 15+ extra cycles.
Odor-free and low volatiles for safe use in enclosed spaces.
Product Introduction
T80A silane impregnating agent excels as a paste for concrete in extreme conditions. With isooctyltriethoxysilane at minimum 80%, it creates a breathable, hydrophobic barrier within pores, resisting water, chlorides, and alkalis. Perfect for coastal structures, parking garages, and industrial floors, it prevents corrosion and spalling while allowing moisture vapor to pass. This formulation supports long-term integrity in pollutant-heavy or acid rain-prone areas, without forming a surface film.
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
Clean and dry the surface, removing any efflorescence or prior sealers. Apply T80A in thin layers via trowel or brush, at 250-450 g/m².
Surface dries in 1-3 hours, with full cure in 5-7 days.
Use between 8-35°C and under 80% humidity. Effective for coastal buildings, garages, and silos to defend against water absorption, salts, and environmental wear.
