    Abstract: An article generally comprises an epoxy base coat and a urethane top coat which has particular use for application. The epoxy composition is generally a two-part, 100 percent volatile-free system containing one or more hardeners which are reacted with an epoxy component such as the glycidyl ether of bisphenol-A. The urethane composition is also generally a two-part, 100 percent volatile-free system containing a polyisocyanate component and an intermediate component comprising a polylactone polyol, and/or a polyether polyol, a polyester polyol, or a polyether-ester polyol, an aliphatic polyol chain extender and a moisture scavenger. The two-part epoxy composition can be applied to a road with the urethane composition coated thereon whereupon it serves as a lane marker. The urethane composition has exceptional weatherability, abrasion-resistance and non-yellowing characteristics.
