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. Various reflective compounds such as glass beads can be applied thereto which are partially embedded therein and have good night as well as wet night reflective properties.

An article comprising a cured epoxy layer and a cured urethane layer in contact with and intermingled with said epoxy layer, said epoxy layer derived from a mixture of a two-part liquid epoxy coating composition comprising an epoxy resin part and a part of at least one epoxy hardener and containing less than 10 weight percent volatiles, said epoxy layer cured at ambient temperature or higher and having an equivalent ratio of said hardener to said epoxy resin of from 0.75 to 1.05 said urethane layer derived from the reaction mixture of a two-part urethane composition comprising a first part of an intermediate component comprising at least one polyol intermediate and optionally a moisture scavenger and a second part comprising a polyisocyanate component, said urethane layer cured at ambient temperature or higher, and said urethane composition containing less than 10 wt. % volatiles.
