A rotted wood stabilizer composition is provided, the composition comprising: from about 75 to about 90 weight percent of a crosslinking polymer; from about 1.5 to about 0.5 to about 1.5 weight percent of a film forming agent, and from about 8 to about 15 weight percent water, and optionally further comprising a biocide and a defoamer. The composition preferably has a pH in the range of from about 2.8 to about 3Ø Further the composition preferably has a viscosity of between about 750 to about 1250 cps as measured on a BROOKFIELD RV viscometer (helipath on) with a #2 T/E spindle at about 12 rpm and about 25°C. The invention further provides for methods of manufacturing the composition, as well as for methods of repairing a rotted area of a wood component by applying the composition of the present invention.
L'invention concerne une composition de stabilisation du bois en putréfaction, comportant un pourcentage massique compris entre 75 % et 90 % environ d'un polymère de réticulation, entre 0,5 % et 1,5 % environ d'un agent filmogène, et entre 8 % et 15 % environ d'eau; de plus, elle peut comprendre un biocide et un agent antimousse. Il est préférable que la composition ait un pH compris entre 2,8 à 3,0 environ. Il est de plus préférable que la composition ait une viscosité comprise entre 750 et 1 250 cP environ, tel que mesuré sur un viscosimètre BROOKFIELD RV (système Helipath en fonction), avec un rotor mobile T-E no 2, à un régime d'environ 12 tr/min et à une température d'environ 25 degrés C. L'invention concerne également les méthodes de fabrication de la composition, de même que les méthodes de réparation d'une surface putréfiée d'un élément en bois en appliquant la composition de la présente invention.
