Title (EN) SILICONE WOUND DRESSING LAMINATE AND METHOD FOR MAKING THE SAME
(FR) STRATIFIÉ DE PANSEMENT DE SILICONE ET PROCÉDÉ DE FABRICATION DE CELUI-CI
Abstract: front page image
(EN)A method of making a wound dressing comprising the steps of: providing an apertured substrate layer; coating the substrate layer with a fluid silicone prepolymer composition; thermally partially curing said silicone prepolymer composition to form a partially cured silicone coating on the substrate; laminating the coated substrate layer to a base layer to form a laminate having said partially cured silicone coating in contact with a surface of the base layer; followed by exposing the laminate to ionizing radiation, to further cure the partially cured silicone coating and to bond the silicone coating to said surface of the base layer. The radiation cure results in strong bonding between the siliconized substrate and incompatible base layers such as polyurethane foams. Also provided are wound dressings obtainable by the process of the invention.
(FR)L'invention concerne un procédé de fabrication d'un pansement, qui comprend les étapes consistant à: prévoir une couche de substrat pourvue d'ouvertures; enduire la couche de substrat d'une composition de prépolymère de silicone fluide; faire durcir partiellement, par des moyens thermiques, ladite composition de prépolymère de silicone afin de former un revêtement de silicone partiellement durci sur le substrat; stratifier la couche de substrat enduite sur une couche de base pour former un stratifié, qui comporte ledit revêtement de silicone partiellement durci en contact avec une surface de la couche de base; exposer ensuite le stratifié à un rayonnement ionisant pour durcir davantage le revêtement de silicone partiellement durci et lier celui-ci à ladite surface de la couche de base. Le traitement par rayonnement permet de former une liaison forte entre le substrat siliconé et des couches de base incompatibles, telles que des mousses de polyuréthanne. L'invention concerne aussi les pansements obtenus à l'aide du procédé de l'invention.
