Patent ID: 8337977

Claim:
An elastic and resilient film for application to a surface of an endless moving handrail, comprising: a first layer having a top surface and a bottom surface and having sufficient resilience to accommodate strains occurring on the surface of the endless moving handrail, the first layer having a first adhesive on the bottom surface and a first barrier coating on the top surface, the first barrier coating having sufficient resilience to accommodate strains occurring on the surface of the endless moving handrail and retarding the transmission of staining chemicals blooming from the endless moving handrail, the first barrier coating comprising nano-clay dispersed in an elastomeric material, the elastomeric material being selected from one of neoprene, nitrile rubber, and butyl rubber; a second layer having a top surface and a bottom surface being disposed on the top surface of the first layer, the second layer having sufficient resilience to accommodate strains occurring on the surface of the endless moving handrail, and further having a second adhesive on the bottom surface of the second layer; and a transparent layer overlying the top surface of the second layer, the transparent layer having sufficient resilience to accommodate strains occurring on the surface of the endless moving handrail.
