A wood preservative composition resulting from admixing components comprising: at least one preservative metal; a quaternary ammonium compound; at least 2 amine compounds; a pH reducing agent, and water, wherein the pH of the composition is from about 7.1 to less than 8.5. Surprisingly, this combination of materials results in a stable solution that can contain a moldicide yet have a commercially acceptable shelf life.
L'invention concerne une composition de préservation du bois issue du mélange de composants comprenant : au moins un métal de préservation ; un composé ammonium quaternaire ; au moins deux composés amine ; un agent réducteur du pH et de l'eau. Le pH de la composition est compris entre environ 7,1 et moins de 8,5. Il est surprenant de constater que cette combinaison de matériaux permet d'obtenir une solution stable qui peut contenir un produit de protection tout en ayant une durée de conservation commercialement acceptable.
