BYK-UV 3519

BYK UV 3519 is a nano-particle dispersion based on surface-treated silica that improves the scratch and abrasion resistance of solvent-free and solvent-borne radiation curable clearcoats. BYK UV 3519 offers the highest level of scratch and abrasion resistance without negatively impacting properties such as gloss and transparency. It improves impact resistance and increases the flexibility of radiation curable clearcoats. The UV-reactive modification crosslinks the nano-particles with the binder, further increasing the hardness of coatings. The combination of improved hardness and flexibility enhances the selection of potential binders and monomers, even when they show strong shrinkage. BYK UV 3519 is recommended for applications that require maximum durability, protection and longevity.
