Perma-New™ V-​​​16 (​​​​​​​​UV-cur​​ed) Class Coatings are new formulations similar to Perma-New V-2, but this class can be optimized for adhesion of vacuum deposited coatings (anti-reflective coatings) that will be applied on top. Although the V-2 class coatings can be used for subsequent vacuum deposition, it is easier for the vacuum deposition operator to achieve good adhesion over formulations in this class. The solids of this coating technology can be as high as 46%, which makes them suitable for spin application on ophthalmic lenses. At lower solids, coatings of this class can be used for dipping, roller or flow applications.

Perma-New™ V-2 Class (UV-c​​ured) Coatings are proprietary formulations of UV-curable monomers in alcohol solvents. Typically, they will be colorless to pale amber liquids containing 20-50% solids (i.e., polymerizable and non-volatile materials, not including solvents). The percentage of solids is adjusted to match the intended application method. These coatings will adhere to many kinds of plastics without requiring a primer. At a target thickness of 4 to 12 microns, when fully cured, this class of coating will resist 5 double rubs under firm thumb pressure with #0000 steel wool, with few or no visible scratches. even on polycarbonate. Taber abrasion resistance on acrylic or polycarbonate will be outstanding compared to uncoated plastic.

Perma-New™ V-17 (U​V-cured) Class Coatings comprise weatherable coating technology for polycarbonate. Although our Perma-New 6000 class of coatings provides great outdoor service on acrylic, polycarbonate is so susceptible to UV degradation, that it needs special protection. Otherwise the hardcoating loses adhesion as the polycarbonate degrades underneath it. This new technology is UV-curable and is expected to provide 5 years of outdoor performance, based on QUV test results. Coating formulations of this class can be optimized for spray, flow, roller or dip applications.

Perma-New™ 6000 Class Coatings is a patented technology incorporating silica-filled methylpolysiloxane polymer containing a latent heat-cure catalyst system, in a blend of alcohols. They are colorless, slightly hazy liquids, typically containing 28% solids by weight. Solids content can be reduced to accommodate different application techniques.

Perma-New™ 4000 Class Coatings strike an optimal balance between hardness and resistance to fogging. These are proprietary formulations of a polysiloxane (silicone) copolymer in alcohol solvents, which can be heat-cured to a hard, transparent, coating that has excellent resistance to fogging. At a target thickness of 3.5 to 5 microns on polycarbonate, it will resist rubs with “#0000” steel wool at least 5 times as well as uncoated polycarbonate.
