Assignee:
PPG INDUSTRIES OHIO, INC. - Cleveland OH
International Classification:
C08G 18/00
US Classification:
528044000
Abstract:
The present invention relates to a polyether-containing polyureaurethane lens. The polyureaurethane lens can include a prepolymer comprising a polyisocyanate and a polyether-containing polyol material that can be reacted with an amine-containing curing agent to produce the polyureaurethane lens of the present invention. The polyether-containing polyureaurethane lens can have a hard coating on both surfaces and a maximum center thickness of 2.2 mm in a piano configuration, with an impact resistance of at least 148 feet per second as defined by The High Impact Test.
