Application Methods
VueGuard® 911AG may be applied via spray (hand or automated), dip, roll or flow coating.
Weatherability
VueGuard® 911AG coatings provide resistance to or retardation of the degrading effects of UV in sunlight as well as certain other effects of weathering. This coating will resist the yellowing of plastic from sunlight permitting extended uses in UV exposure. Polycarbonate coated sheets and parts have exceeded 3,000 hours in the QUV accelerated weathering tester (Q Panel Corporation) using ASTM G-53 test method.
Chemical Resistance
VueGuard® 911AG coated products have excellent resistance to many chemicals. They will resist diluted sulfuric acid, alcohols, aromatic solvents such as toluene and xylene, trichloroethylene and gasoline.
Scratch & Abrasion Resistance
VueGuard® 911AG coatings deliver an extended service life when compared to uncoated substrates while maintaining an attractive appearance. Tests conducted using PCI Labs' steel wool scratch tester show no sign of scratching at 12 psi using a #0000 steel wool pad at five rotations.
Glare Reduction Levels
Various levels of glare reduction are available to enhance readability. They range from 0° gloss level to 85° gloss level with the most popular being 32°, 54° and 75° gloss units. Selection of a specific gloss level is dependent upon the type of display being used and glare reduction sought.
Surface Printing
Surface printing over VueGuard® 911AG coated products is feasible by using our proprietary surface treatment PST-1126.
Cleaning Instructions
VueGuard® 911AG coated sheets and fabricated parts may be cleaned using ordinary liquid window cleaners and a soft cloth.
