Newer ultrafine nepheline syenite sizes have refractive index and physical properties that are particularly well suited for use as a performance additive in radiation-curable coatings, inks and adhesives.
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.
