System, method and composition for adhering preformed thermoplastic traffic control signage to pavement
First Claim
1. A system for coating a substrate and bonding a marking tile to said substrate, wherein a polyurea epoxy curable primer composition of about 200 centipoise comprises a sealing layer that is bonded directly to said substrate and, wherein said sealing layer bonds with an additional bonding layer comprising an epoxy bonder paste in a range of 10,000 to 300,000 centipoise, said wherein said sealing layer and said additional bonding layer provide a combined adhesive layer coating and covering of said substrate, wherein said substrate and said combined adhesive layer coating and covering provides for further bonding to a preformed thermoplastic marking tile that is applied over said additional bonding layer, thereby forming a single, semi-homogeneous, permanent pavement marking.

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.
