Title
(EN) BINDER FOR PRODUCING WOOD-BASED COMGLOMERATES WITHOUT RELEASE OF FREE FORMALDEHYDE AND METHOD FOR MAKING THE BINDER
(FR) LIANT POUR LA PRODUCTION DE CONGLOMÉRATS À BASE DE BOIS SANS LIBÉRATION DE FORMALDÉHYDE LIBRE ET PROCÉDÉ DE FABRICATION DU LIANT
Abstract
(EN)
A binder for producing wood-based conglomerates without release of free formaldehyde, said binder having a total mass by weight, the total mass comprising a first quantity by weight of a compound selected from urea- formaldehyde or melamine-formaldehyde, the total mass by weight comprising a second quantity of a humic substance, which by weight is complementary of the first quantity.
(FR)
L'invention concerne un liant pour la production de conglomérats à base de bois sans libération de formaldéhyde libre, ledit liant ayant une masse totale en poids, la masse totale comprenant une première quantité en poids d'un composé choisi parmi l'urée-formaldéhyde ou le mélamine-formaldéhyde, la masse totale en poids comprenant une seconde quantité d'une substance humique, qui en poids est complémentaire de la première quantité.
