SYNTACTIC SEALANTS 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/m3 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. |
