    Abstract: An adhesive which includes at least one silane-functional polymer P; at least one catalyst for crosslinking silane-functional polymers, the catalyst being selected from the group including organo-titanate, organo-zirconate, and organo-aluminate; at least one base; and at least one adhesive selected from alkoxy mercaptosilane and amino alkoxysilane, for filling wood joints. The adhesive filled into the joints is preferably sanded after the curing process. The adhesive exhibits a high UV stability and a stability against warm humid climates. The adhesive is therefore suitable for naval applications in particular, such as in the construction of boats and ships. The adhesive can be formulated so as to be black, white, or gray for example.

    Abstract: A composition including: —at least one silane group-containing polymer with a silicon content ranging from 0.6 to 2 wt. %, obtained by reacting at least one isocyanate group-containing polymer and at least one amino-, mercapto-, or hydroxysilane, —at least one liquid epoxy resin, and—at least one polyamine with at least three amine hydrogens which are reactive towards epoxy groups. The composition facilitates adhesives, coatings, or sealing compounds with a good storage stability, a fast curing time, even in the event of moisture or humidity, a surprisingly high degree of strength while having a high degree of elasticity, a high degree of resistance against further tearing, a high degree of resistance in particular against glycol/water mixtures, and a high degree of adhesion to many substrates. When used on metals such as steel or aluminum, the composition protects same against corrosion.

    Abstract: A moisture-curable composition, including between 0.6 and 15.0 wt.-% of at least one organic polymer containing reactive silane groups, between 70 and 95 wt.-% of at least one filler, at least one dispersion additive, optionally at least one catalyst for the curing of silane-functional polymers and up to 10 wt.-% of at least one plasticizer, characterized in that said filler is selected from the list consisting of aluminium oxide, aluminium hydroxide, boron nitride, aluminium nitride, zinc oxide, silver, copper, aluminium, chalk, aluminosilicate, graphite, and any mixture of these fillers; with the proviso that the amount of chalk in the filler does not exceed 25 wt.-% of the total amount of filler. The moisture-curable composition shows excellent thermal conductivity and is particularly suitable as adhesive, gap filler, or sealant suitable for e-coat applications and battery bonding especially in electric automobile assembly.
