Abstract:
An article is provided consisting of an epoxy base coat and a urethane top coat which is useful in pavement marking applications. The epoxy composition is 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 a two-part, 100 percent volatile free system containing a polyisocyanate component and an intermediate component comprising a polylactone polyol, and/or a polyether poloyl, 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 thereof whereupon it serves as a lane marker. The urethane composition exhibits weatherability and abrasion-resistance and has non-yellowing characteristics. Various reflective compounds such as glass beads can be applied and partially embedded therein to provide night and wet night reflectivity.
