Abstract
A method of manufacturing an elastic and resilient film, to be applied to a surface of an endless moving handrail, includes providing a first layer having sufficient resilience to accommodate strains occurring on the surface of the endless moving handrail, and including a barrier coating. The barrier coating includes nano-clay dispersed in an elastomeric material selected from one of neoprene, nitrile rubber, and butyl rubber. A substantially transparent layer is also provided. The first layer and the substantially transparent layer are laminated together. Optionally, a second layer is arranged between the first layer and the substantially transparent layer. The barrier coating substantially retards the transmission of staining chemicals blooming from the surface of the endless moving handrail.
