A low-VOC silanol additive is provided for a wide range of silane treatment operations, including treating cellulose fibers in fiber cement applications. The silanol additive is made by hydrolyzing silane at the presence of a catalyst and then removing substantially all of the VOCs, such as alcohol, that are released by the hydrolysis reaction to produce a low-VOC and/or substantially alcohol-free silanol additive. The low-VOC silanol additive can be used in various industrial processes without increasing the VOC emission at the manufacturing facility. The silanol additive can be directly applied to the treated surface so as to eliminate the reaction time needed for hydrolyzing silane in most conventional silane treatment processes. The silanol additive can be added to a solution containing the treated substrate or directly applied as a surface treatment.

L~invention porte sur un additif silanol à faible VOC pour une vaste gamme d~opérations de traitement de silane, englobant le traitement de fibres de cellulose dans des applications de ciment en fibre. L~additif silanol est réalisé par hydrolyse de silane en présence d~un catalyseur, puis par enlèvement de pratiquement tous les VOC, comme l~alcool, qui sont libérés par la réaction d~hydrolyse pour produire un additif silanol à faible VOC et/ou sensiblement sans alcool. L~additif silanol à faible VOC peut s~utiliser dans divers processus industriels sans augmenter l~émission de VOC sur le site de fabrication. L~additif silanol peut être appliqué directement à la surface traitée pour éliminer le temps de réaction nécessaire à l~hydrolyse du silane dans la plupart des processus de traitement de silane conventionnels. L~additif silanol peut s~ajouter à une solution contenant le substrat traité ou être appliqué directement comme traitement de surface.
