Abstract
An article includes a substrate with two main faces defining two main surfaces separated by edges, the substrate carrying a functional coating deposited over at least a portion of a main surface and a temporary protective layer deposited over at least a portion of the coating. The temporary protective layer has a thickness of at least 1 micrometer. The temporary protective layer made of polyfuran resin is obtained from a liquid composition comprising furfuryl alcohol.
Claims19
An article comprising a substrate comprising two main faces defining two main surfaces separated by edges, said substrate carrying:
- a functional coating deposited over at least a portion of a main surface and
- a temporary protective layer deposited over at least a portion of the functional coating, wherein:
- the temporary protective layer has a thickness of greater than 1 micrometer,
- the temporary protective layer comprises or consists essentially of a poly(furfuryl alcohol) resin.
A process for the protection of an article comprising a substrate comprising two main faces defining two main surfaces separated by edges, said substrate carrying a functional coating deposited over at least a portion of a main surface, said protection process comprising the following stages:
- preparing a liquid composition comprising furfuryl alcohol,
- applying the composition to at least a portion of the functional coating over a thickness of at least 1 micrometer,
- polymerizing the composition so as to form a temporary protective layer a poly(furfuryl alcohol) resin.
