T99 silane impregnating agent is a high-performance penetrating sealer based on n-butyltriethoxysilane, designed for long-lasting concrete protection without altering surface appearance.
Summary Benefits at a Glance:
Deep penetration up to 3mm in ordinary concrete for robust hydrophobic barrier.
Reduces chloride absorption by over 90% to prevent corrosion.
Maintains breathability to avoid moisture buildup and efflorescence.
Product Introduction
T99 silane impregnating agent provides advanced protection for concrete and cementitious surfaces.
Formulated with high-purity n-butyltriethoxysilane, it penetrates deeply into pores to form a hydrophobic, cross-linked structure.
This non-film-forming approach repels water and contaminants while allowing vapor to escape, making it suitable for structures like bridges, highways, and marine installations.
With a silane content of at least 98%, it offers reliable defense against environmental damage, extending the lifespan of concrete without changing its look or texture.
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
Prepare the surface by cleaning off dust, oil, and old coatings; ensure concrete is dry and at least 28 days old.
Apply T99 using a low-pressure sprayer or roller in one or two wet-on-wet coats, with coverage of 200-400 g/m² based on porosity.
Allow 1-2 hours for surface drying and 24-48 hours for full cure at 20°C. Best applied between 5-35°C, avoiding rain or high humidity.
Ideal for protecting bridges, facades, and industrial floors from water and chloride damage.
