Abstract

Une dispersion dacide borique et/ou durée aqueuse comprend des particules dacide borique insolubles dont la plage de la taille médiane est inférieure à 44 micromètres et dont le pourcentage de composition active dacide borique et durée est dau moins 60 % en poids. La dispersion dacide borique et/ou durée comprend également les éléments suivants : au moins 1 agent de réduction de la viscosité à une concentration efficace de sorte que la viscosité statique initiale obtenue par viscomètre Brookfield à 2 tours par minute est entre environ 5 000 et 25 000 centipoises, et que la viscosité obtenue par viscomètre Brookfield à 2 tours par minute au bout de 3 semaines est inférieure à 250 000 centipoises; un montant facultatif dune base de métal alcalin dans lequel le rapport molaire entre la base de métal alcalin et lacide borique dans la dispersion est entre 0,00 et environ 0,01; un montant deau qui représente la partie restante. En plus de représenter une partie d'une formulation de revêtement à leau servant de revêtement ignifuge pour les produits de bois, la dispersion dacide borique et/ou durée peut servir dans la fabrication de produits de bois dingénierie comme les panneaux de lamelles orientés.
