NANOBYK-3652 is a nanoparticle dispersion that improves the scratch resistance of solvent-borne clear coatings. It contains surface-treated silica nanoparticles with a typical particle size of 20 nm. NANOBYK-3652 provides the so-called "immediate reflow effect" due to the evenly distributed silica nanoparticles. They absorb impacting energy and release it slowly, resulting in an elastic surface with consistent hardness. Mechanical impact leaves little trace and the surface remains virtually undamaged, providing perfect long-term protection. This makes NANOBYK-3652 well-suited for applications that require durable, scratch-resistant coatings.
