Coatings Industry: The additive provides the so-called “immediate reflow effect” due to the silica nanoparticles which are evenly distributed in the coating and which act like shock absorbers. They absorb the impacting energy and only release it very slowly. This results in an elastic coating surface with a consistent hardness. Mechanical impact leaves hardly any trace and the coating surface is virtually undamaged. It therefore provides perfect long-term protection.

The product reaches its full effectiveness when added at low shear forces. This ensures that even distribution in the binder system is achieved. It is recommended that all surface active compounds in the formulation are removed, as silicones which reduce the surface tension in order to improve the substrate wetting, anti-cratering properties and surface slip, are not generally required when using the NANOBYK additive. If necessary, the leveling can be optimized later on using acrylate or silicone additives which have no effect or only a very minor effect on the surface tension.
