Patent ID: 8216679

Claim:
A glazing assembly comprising: a plastic panel having a first side surface and a second side surface; a first protective coating system deposited on the first side surface, the first protective coating system further comprises a weathering layer and at least a first abrasion-resistant layer on the weathering layer and a second abrasion-resistant layer on the first abrasion-resistant layer; a second protective coating system deposited on the second side surface, the second protective coating system further comprises a first abrasion resistant layer comprising a vinyl-D4 layer on the second side surface and a second abrasion-resistant layer on the first abrasion-resistant layer; and wherein the first and second protective coating systems each provide a different amount of protection from weathering and abrasion to the plastic panel from the first and second side surfaces, respectively; wherein a weathering layer and a primer layer are not provided between the first abrasion-resistance layer of the second protective coating system and the second side surface; wherein the abrasion resistant layers are vacuum deposited layers and the first abrasion-resistant layer of the second protective coating system includes a UV absorbing species formed from a reactive species; wherein at least one of the abrasion resistant layers of the second protective coating system is different in composition from the abrasion resistant layers of the first protective coating system.
