We have in store for our clients an extensive array of Water Repellent Coating also known as EXCEL NanoSeal. These are a nanotechnology based hydrophobic agents which are designed to impart water repellency to wide variety of substrates. Incorporated with latest technology, these Coatings are designed for prevention, repair and maintenance of buildings. Our NanoSeal is a boon to prevent and repair cracks, swelling, shrinkage and other damages caused due to penetration of water.
EXCEL NanoSeal by its name indicates, is a nano technology based water repellent. Unlike various film of coating, EXCEL NanoSeal does not seal the pores at the surface of concrete. But it penetrates into the pores and forms a very thin layer (nano Layer) on the pore walls. These pores no longer be wetted by water and the capillary uptake of water is prevented. Water can no longer penetrate inside through capillaries, as water is a polar liquid and it cannot reach with non polar, hydrophobic surface.
Untreated surface of buildings are wetted immediately by water. In other words, drops of water spreads out and rapidly absorbed by building material. The surface treated with EXCEL NanoSeal, the drop of water is repelled and stands in the form of bead and doesnot penetrate inside. The pores on the surface may vary from 5 Ã¢â‚¬â€œ 200 nm. But the size of EXCEL NanoSeal is 4 Ã¢â‚¬â€œ 6 nm (0.005 micron).
Conventional water repellents give only a short term protection by forming a surface film. Long term protection is possible only by nano sized water repellent, which penetrates up to 4 Ã¢â‚¬â€œ 5 mm into the surface providing capillary coating. The life expectation on the coatings is 20+ years.
