Adhesive backed preformed thermoplastic sheeting
View Patent ↗The present invention relates to a system, method, and composition utilizing a pressure sensitive adhesive (PSA) and/or thermal sensitive adhesive sheet for adhering sheets of preformed thermoplastic road markings, texture and design patterns to concrete, asphalt, wood or composite material surfaces. These markings may be decorative or legend type markings. The system involving the method of applying the product allows for immediate use in a traffic area upon completion of the application to any of the appropriate outdoor surfaces.
1. An outdoor pavement marking system consisting essentially of at least two preformed thermoplastic sections including top sides with textures and design patterns and bottom sides with adhesive backed sheeting residing on said bottom sides of said preformed thermoplastic sections; and;
a single protective sheet that covers said sheeting on the bottom side;
wherein said protective sheet comprises a silicone elastomer covering said sheeting and wherein said bottom sides of the preformed sections are subsequently adhered to any suitable outdoor surface after removing said protective sheet from said adhesive backed sheeting and using at least pressure to provide the bond strength necessary to ensure a proper surface covering, wherein said suitable outdoor surface includes thermoplastic road markings, and wherein said preformed thermoplastic sections form a decorative layer; wherein said preformed thermoplastic sections are abutted with said sheeting underlying the abutted portion to help form said decorative layer capable of withstanding exposure to outside weather elements and wherein said decorative layer contains particles causing a suitable outdoor abradable resistant surface for road markings, walkways, and other outdoor surfaces and wherein the chemical composition of said adhesive layer used for said sheeting is either alkyl or butyl based.
2. The system of claim 1 , wherein said preformed thermoplastic sections are matched with at least one other preformed thermoplastic section such that said decorative layer provides a desired pattern.
3. An outdoor pavement marker product consisting of an adhesive backed sheeting; wherein the adhesive back sheeting has at least two preformed thermoplastic sections comprising top sides with textures thereby forming a decorative layer and bottom sides with a single, continuous curable resin adhesive layer over a primer layer underlying the at least two preformed sections; said adhesive layer, said primer layer and said at least two preformed thermoplastic sections together forming said adhesive backed sheeting;
and;
a single protective sheet that covers said adhesive backed sheeting on said bottom side; wherein said protective sheet comprises a silicone elastomer that covers said adhesive backed sheeting on said bottom side such that said protective sheet is removable and allows for required adhesion of said bottom side to any suitable outdoor surface after removing said protective sheet from said adhesive backed sheeting and using at least pressure to provide the bond strength necessary to ensure a proper surface covering of said pavement marking system, wherein said suitable outdoor surface includes concrete, asphalt, wood or composite material surfaces; the at least two preformed thermoplastic sections are abutted with said adhesive backed sheeting underlying the abutted portion, said decorative layer is capable of withstanding exposure to outside weather elements and wherein said decorative layer contains particles that provide for suitable outdoor abradable resistant surfaces for road markings, walkways, and other outdoor surfaces and wherein the chemical composition of said adhesive layer used for said adhesive backed sheeting is either alkyl or butyl based.
4. The preformed thermoplastic sections of claim 3 , wherein said thermoplastic sections are matched with at least one other preformed thermoplastic section such that said decorative layer provides a desired pattern.
