Patent

CA 2739686

The invention relates to a method for coating, gluing or connecting surfaces of mineral materials with a two-component plastic resin, selected from a hydrophobic polyurethane resin and a hydrophobic epoxy resin, by applying the plastic resin on the surface or connecting the surfaces of the mineral materials with the plastic resin and by leaving the plastic resin to harden. The invention is characterized in that the plastic resin contains 0.01 to 10 percent by weight of one or more hydroxy or alkoxy aminosilane compounds of general formula (I), wherein X independently of one another represents OH, CH3, O[CH2]p CH3; Y = [CH2]t, [CH2]r NH[CH2]s; R, R' H, [CH2]t CH3; t = 0 - 10; n = 1- 3; p = 0 - 5; m = 4 - n; r, s independently of one another represent 1-10.

L'invention concerne un procédé pour enduire, coller ou relier les surfaces de matériaux minéraux avec une résine plastique bicomposant sélectionnée parmi une résine de polyuréthane hydrophobe et une résine époxy hydrophobe, par application de la résine plastique sur la surface des matériaux minéraux ou liaison des surfaces des matériaux minéraux avec la résine plastique et durcissement de la résine plastique. Le procédé selon l'invention est caractérisé en ce que la résine plastique contient 0,01 à 10 % en poids d'un ou de plusieurs composés hydroxy aminosilane ou alcoxy aminosilane de formule générale (I) dans laquelle X représente OH, CH3, O[CH2]pCH3, Y représente [CH2]t, [CH2]rNH[CH2]s, R et R' représentent H, [CH2]tCH3, t vaut 0 à 10, n vaut 1 à 3, p vaut 0 à 5, m vaut 4 à n et r et s valent indépendamment l'un de l'autre 1 à 10.
