NANOBYK 3620 is a VOC-free, aqueous dispersion made up of nanohybrid particles that protects glossy surfaces against scratching and abrasion. It contains surface-treated silica nanoparticles dispersed in water. NANOBYK 3620 improves the abrasion and scratch resistance of aqueous, glossy coatings. This protective property comes into effect quickly after only a brief drying period. NANOBYK 3620 has no negative influences on the gloss and transparency, and is therefore particularly suitable for clear coats. It is easy to incorporate and should be stirred into the coating. NANOBYK 3620 does not settle and therefore requires no stirring before use. For the industries that require glossy, scratch-resistant coatings on surfaces, NANOBYK 3620 provides benefits like early scratch resistance without impacting pot life and maintaining gloss and transparency of coatings.
