Nanolex Ultra Glass Sealant is a silica-based coating that forms a hydrophobic (water-hating) barrier layer on automotive glass. It achieves this by laying down a thin layer of nano-scale silica components and functional additives that harden to form a fully transparent micro-film that repels rain, sleet and snow upon contact. As a result, rain drops and road spray simply bead up and roll off of treated surfaces, and are blown off by the wind when driving speeds rise above 30 mph. Moreover, this beading also tends to pick up and carry away fresh dirt and grime, meaning that the coating is partially self-cleaning (akin to the Lotus Effect in nature). The net effect of all of these benefits is that Nanolex Ultra Glass Sealant significantly improves visibility and driving comfort in poor weather conditions, and greatly reduces the need to use windscreen wipers and screen wash. Furthermore, in the summer months bug splatter washes off with ease, and in the winter de-icing is more quickly achieved.
