Title
(EN) FIRE RESISTANT COATINGS FOR WOOD VENEER PANELS
(FR) REVÊTEMENTS RÉSISTANTS AU FEU POUR PANNEAUX EN BOIS PLAQUÉ
Abstract
(EN) Methods for treating panels are described that include coating a wood substrate with a polymeric solution, curing the coated wood substrate by subjecting the coated wood to ultraviolet radiation and causing the polymeric solution to crosslink to produce a fire-resistant veneer. Also described is a composite material comprising a wood substrate layer, and a UV-cured flame retardant coating the wood substrate layer, wherein the composite material has a Flame Spread Index values within 0 to 25 and a Smoke Developed Index of 450 or lower.
(FR) La présente invention concerne des procédés de traitement de panneaux qui consistent à revêtir un substrat ligneux avec une solution polymère, à durcir le substrat ligneux revêtu par exposition du bois revêtu à un rayonnement ultraviolet et à amener la solution polymère à réticuler afin de produire un placage résistant au feu. La présente invention concerne également un matériau composite comprenant une couche de substrat ligneux, et un agent ignifuge durci par rayonnement UV revêtant la couche de substrat ligneux, le matériau composite ayant une valeur d’indice de propagation des flammes comprise entre 0 et 25 et un indice de dégagement des fumées inférieur ou égal à 450.
