ABSTRACT:
The present novel organosilicon compound is a 2-trimethoxysilylpropionate represented by the following formula ##STR1## wherein R represents a monovalent hydrocarbon group having 6 to 12 carbon atoms. This ester reacts efficiently with alcohols and silanols and is useful, for example, as a terminal alkoxysilylating agent for organopolysiloxanes such as industrially useful .alpha.,.omega.-dihydroxypolydimethylsiloxane, or as a surface treatment for silicas, or as a storage stabilizer that serves as a scavenger of an alcohol for alcohol elimination type RTV. Further, since the present organosilicon compound is a three-functional alkoxysilane having three methoxy groups in the molecule, it is useful as a curing agent for alcohol elimination type RTV.
