Fluorine-containing organosilicon compound

Abstract

Fluorine-containing organosilicon compound according to the present invention is expressed by the general formula: ##STR1## wherein Rf is a perfluoropolyether group having 3 to 17 carbon atoms, R is an alkylene group having 1 to 6 carbon atoms or a group of the general formula, --R.sup.2 --O--R.sup.3 --, wherein R.sup.2 and R.sup.3 may be the same or different and are each alkylene groups having 1 to 6 carbon atoms. The present compound is useful as a curing catalyst for organo-polysiloxane compounds that are condensation curable at room temperature. The compositions added with the fluorine-containing organosilicon compound have excellent characteristics such as water and oil repellencies, chemical resistance and contamination resistance and offer a variety of uses such as high performance sealing, coating and electric insulating materials.
