  • Patent number: 7753616
    Abstract: The present disclosure relates to a system and permanent pavement marker for coating or bonding or both coating and bonding a first underlying substrate, wherein a second layer comprises a polyurea epoxy curable composition of about 200 centipoise which is bonded to the first underlying substrate, wherein the curable composition second layer is further bonded to a third layer, wherein the third layer comprises an epoxy bonder paste in a range of 10,000 to 300,000 centipoise, and the third layer is further bonded to a fourth layer, wherein the fourth layer is a preformed thermoplastic marking tile that is applied over the third layer of epoxy bonder paste, thereby forming a the permanent pavement marking. The system and pavement marker may also include a thermoplastic adhesive applied between the epoxy bonder paste and the preformed thermoplastic marking tile such that the bonder paste acts as a water vapor barrier reducing the rate of water vapor transmission into the marking tile.

  • Patent number: 7744306
    Abstract: Disclosed is an alkyd resin-based pre-manufactured thermoplastic airport runway signage that is applied in relatively large sections onto an airport runway. The pre-manufactured preformed thermoplastic formed as a continuous sheet and wound onto a take-up spool. The runway surface is prepared with a CCS epoxy primer and the preformed thermoplastic is unwound from the take-up spool and positioned onto the runway surface. When the pre-manufactured thermoplastic signage is in a desired location it is initially rolled conforming to the runway surface. Heat is applied to the rolled surface to a preferred temperature with an infra-red (IR) heater to melt and adhere the pre-manufactured thermoplastic signage into the runway surface.

  • Patent number: 7465693
    Abstract: The present invention relates to a system, method, and composition for a thermochromatic, color indicative sheet or device that is bonded to an article such as a concrete or asphalt surface, a traffic sign, a plate of a guidepost and on which is indicated a surface temperature near or below the freezing point of water. The invention can also utilize an adhesive system including a pressure sensitive adhesive (PSA) and/or thermal sensitive adhesive sheet for adhering sheets of preformed thermoplastic with the thermochromatic color indicative sheet to concrete, asphalt, wood or composite material surfaces. The invention includes methods of applying the product allowing for immediate use in a traffic area upon completion of the application to any appropriate outdoor surface.
