Title (EN) EDGE-SEALING OF PLATE MATERIALS
(FR) ETANCHEITE DES BORDS D"UN MATERIAU EN PLAQUE
Abstract:
(EN) A method for edge-sealing of a plate material, in particular a plate material comprising an ordinarily non-moisture-resistant core or base material, the surfaces of which have been made moisture-resistant, for example by coverage with a moisture-resistant laminate. The method comprises providing the edge surfaces of said material with a circumferential layer of a curable resin composition, said resin composition being of a nature which shrinks during curing, and curing said layer of resin composition to form a peripheral coherent and fixed edge moulding.
(FR) Methode pour assurer une protection etanche des bords d"un materiau en plaque, en particulier d, un materiau en plaque comprenant un noyau ou materiau de base non resistant a l"humidite, dont les surfaces ont ete rendues resistantes a l"humidite, par exemple en les recouvrant avec un lamine resistant a l"humidite. La methode consiste a deposer sur les surfaces des bords dudit materiau une couche circonferentielle d"une composition de resine durcissable, ladite composition de resine subissant un retrait lors de son durcissement, et a laisser durcir ladite couche d"une composition de resine pour former un moulage fixe et coherent sur le pour tour des bords.
