Abstract
A coating composition includes a material adapted to form a coating; and a material that fluoresces when exposed to U.V. light or the material adapted to form a coating contains a U.V. blocker disposed on a U.V. indicator. A kit containing a U.V. indicator and material adapted to form a coating containing a U.V. blocker. Methods of coating a substrate with the coating compositions are also disclosed.
Claims46
A coating composition comprising:
- a. a material adapted to form a coating;
- and
- b. a material that fluoresces when exposed to U.V. light.
A coated substrate comprising:
- a. a substrate;
- and
- b. a coating disposed on a portion of the substrate wherein the coating comprising a material adapted to form a coating and material that fluoresces when exposed to U.V. light.
A coated substrate comprising:
- a. a substrate;
- b. a U.V. indicator disposed on a portion of the substrate;
- and
- c. a coating disposed on a portion of the U.V. indicator wherein the coating comprising a material adapted to form a coating and a U.V. blocker.
The coated substrate of claim 24, wherein the intermediate layer is free of U.V. blocker.
A kit comprising:
- a. a U.V. indicator;
- and
- b. a material adapted to form a coating having a U.V. blocker.
A method comprising:
- a. applying a coating composition comprising a material adapted to form a coating and a material that fluoresces when exposed to U.V. light on a portion of a substrate to form a coated substrate;
- and
- b. drying the coated substrate.
