Exterior Coatings

UV radiation is known to contribute to the chemical modification of exposed coating surfaces, resulting in loss of gloss, color change, chalking, and eventually, destruction of the film. NanoArc® Zinc Oxide Dispersions provide superior performance, beyond conventional UV Absorbers for exterior coatings, due to their broad absorption spectrum and long-term stability. In addition to long-term gloss retention and color fastness, NanoArc® Zinc Oxide may also help improve tannin and stain blocking and provide improved coating durability with limited effect on transparency.

Scratch and mar resistance in radiation curable over print varnishes, with no effect on slip or coefficient of friction. Addition of NanoArc® Aluminum Oxide dispersions to OPVs, protects the inks plus adds functionality to magazines, packaging, and other printed materials.

Scratch Resistant Coatings

Formulated into radiation cured or water-based OPVs, NanoArc® Aluminum Oxide dispersions provide mar and scratch resistance for thin, transparent overprint varnishes. Functioning differently than conventional additives, NanoArc® Aluminum Oxide dispersions are active at low loading levels and do not adversely effect gloss. Since they do not migrate to the interfaces, they provide long-term scratch resistance without negatively impacting slip or coefficient of friction.
