<p>Syntactic sealant compositions are obtained from mixing a filled polyorganosiloxane sealant composition which is room temperature curable with ceramic microspheres having a bulk density less than 500 kg/m<3> and organic solvent. These compositions maintain satisfactory handling and storage properties, are extrudable from storage cartridges, and the cured properties are satisfactory for use in sealing voids in building construction.</p> |
