Aliphatic urethanes with high acrylate functionality result in cured films having excellent abrasion resistant properties. The family of UV-PUD materials examined offers a higher reactive solid content at a lower viscosity when compared to typical UV-PUDs on the market.
This paper will review the current use of silica nanoparticles in UV-curable coatings and introduce effective approaches for delivering silica nanoparticles to UV-curable resin formulations without the drawbacks of current solvent- or monomer-based silica nanoparticle dispersions.
