General Informations

Fabric Warranty 10 Years Architectural Permanent Membranes in PVDF/PVC/PES or PTFE/Glass.
Health & Safety An EG Safety Data Sheet is available on this site
Printing Applying artwork to PVC fabric can be done by Vinyl Graphics, Silk Screen Printing or modern Digital Printing. For digital print, please refer to technical data sheet for preparation of artwork.
Cleaning Cleaning Instructions for Membranes can be downloaded in PDF format.
Repairs Normally PVC repairs are undertaken using normal factory welding techniques. However customers can use portable Hot Air Welders or adhesives.

A guide to the Bostik Adhesive System can be downloaded in PDF format.
Acrylic Laquers Protective acrylic layer added on top of the PVC, which means there is a further reduction of plasticizer migration and soiling.
PVDF Laquers This protective layer is the ideal solution to obtain optimal resistance to soiling and to maintain ease of use.
Teflon The PTFE coating has self whitning properties, so long as the membrane is exposed Ultra Violet (UV) Rays. The UV Rays bleach the membrane, thus

keeping it's white surface, however like PVC it will require cleaning. No fabric is self cleaning.
