Nanolex Urban Glass Sealant is a polymer-based sealant for automotive glass that is optimised for low speed driving in urban environments. It works by laying down a film of reactive compounds and a high-tech composite material that cures to form a transparent barrier layer 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 20 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 Urban 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.
