The invention relates to a moisture-curable composition, comprising 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 compostion 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. |
