Abstract

Cette invention concerne la fabrication de produits monocomposants à base de polyuréthane qui s'expanse lors de leurs réticulation. Selon ce procédé, objet de la présence invention, on stabilise un mélange réactif chargé et/ou dilué ou non grâce à un surdosage de la partie polyisocyanate, tout en utilisant cette surdose dans une première étape de fabrication pour la deshydratation des divers composants solides et/ou liquides utilisés comme charge, pigment et solvant. Les domaines d'application sont multiples. Ainsi peut-on fabriquer par exemple des produits monocomposants remplissant après application, aussi bien la fonction d'étanchéité que d'isolement thermique, de joints élastiques qui, grâce à l'expansion ultérieure s'adapteront parfaitement à un diamètre imprécis du joint à remplir, une colle qui à nouveau grâce à l'expansion adhérera sur toutes les surfaces qui par nature n'ont pas de planéité, etc.
