Title
(EN) METHOD FOR MAKING A SMOOTH SURFACE ON A SUBSTRATE
(FR) PROCEDE POUR REALISER UNE SURFACE LISSE SUR UN SUBSTRAT
Abstract
(EN) In order to make a smooth surface by deposition of a thin layer of which the rugosity is one order of magnitude at least lower than that of the substrate, there is used a photopolymerizable varnish capable of wetting evenly the substrate and of which the free surface is either moulded and polymerized by electromagnetic radiation through the transparent wall of the mould whose surface has the desired rugosity, or is formed outside a mould by means of the centrifugal force or by lamellar flow particularly, and polymerized by an electromagnetic or corpuscular radiation such as a beam of electrons.
(FR) Pour réaliser une surface lisse par dépôt d'une couche mince dont la rugosité est d'un ordre de grandeur au moins inférieur à celle du substrat on utilise un vernis photopolymérisable susceptible de mouiller uniformément le substrat et dont la surface libre est soit moulée et polymérisée par un rayonnement électromagnétique à travers la paroi transparente du moule dont la surface présente la rugosité désirée, soit formée en dehors d'un moule à l'aide de la force centrifuge ou par écoulement lamellaire notamment et polymérisée par un rayonnement électromagnétique ou corpusculaire tel qu'un faisceau d'électrons.
