Nanolex - Car Care Products - Premium Spray Sealant Description Nanolex Premium Spray Sealant is an advanced sealant based on nanotechnology that protects and enhances all painted surfaces as well as metal parts and exterior plastics. Nanolex Premium Spray Sealant is based on the chemical sol-gel process that allows to combine nano-scale particles of SiO2 with other reactive components. The compound, which interlaces on the painted surfaces, has a covalent (=permanent) bond to the surface at a molecular level. Surfaces treated with an outstandingly smooth layer of Nanolex Premium Spray Sealant are much more reflective, very hydrophobic and therefore easy to clean. Washing is much easier and less time consuming, cleaning intervals are substantially increased and the overall effort to maintain a flawless finish is heavily reduced by using Premium Spray Sealant.
