T99A silane impregnating agent serves as a specialized penetrating sealer with isobutyltriethoxysilane, offering reliable waterproofing for concrete under severe exposure.
Summary Benefits at a Glance:
Achieves penetration depths of 3mm or more in ordinary concrete for strong hydrophobic defense.
Cuts chloride absorption by at least 90% to combat corrosion.
Supports vapor transmission to prevent internal damage like cracking.
Environmentally compliant with low impact, suitable for indoor and outdoor use.
Product Introduction
T99A silane impregnating agent is engineered for concrete surfaces in challenging environments. Using high-content isobutyltriethoxysilane, it infiltrates pores to create a hydrophobic network that repels water and salts while permitting breathability. This makes it an excellent choice for highways, coastal facilities, and industrial sites where moisture and contaminants pose risks. With over 98% silane purity, it delivers consistent performance, enhancing concrete durability without visible changes to the substrate.
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 the surface thoroughly to remove contaminants and ensure it's dry with less than 4% moisture. Use a sprayer, brush, or roller to apply T99A in uniform coats, covering 150-300 g/m² depending on surface porosity.
It dries to touch in 30-60 minutes and is ready for traffic in 24 hours.
Apply at 10-30°C, steering clear of rain for at least 6 hours afterward.
Great for safeguarding ports, tunnels, and heritage structures from moisture and chloride threats.
