  • Method for controlling wet film thickness of clear coatings by means of color-dissipating dye
    Patent number: 6488719
    Abstract: A method for controlling uniformity of applied film thickness of clear protective coatings by means of a color-dissipatable dye additive which dissipates within a reasonable timeframe, generally from hours to a few days, leaving the applied film with no evidence of its use during the application phase. The color additives temporarily impart color to an otherwise clear coating, and subsequently dissipate over a short period of time. An embodiment of this technology includes the addition of a compatibilizer carrier solution to increase the ease of measuring the dye for addition to the clear coating.

  • Article coated with intermingled epoxy and urethane layers
    Patent number: 5340652
    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.
