ABSTRACT:
Room temperature curing organopolysiloxane composition which are paintable after curing can be made by mixing hydroxyl-terminated organopolysiloxane, a paintability compound which contains at least one X--R.sup.1 --O-- silicon-bonded group and at least one aminoxy or amido group bonded to a silicon atom where X is ##STR1## and R.sup.1 is a divalent hydrocarbon group, and a crosslinking compound which is a silicon compound having at least two silicon-bonded aminoxy and amido groups. These compositions can cure to low modulus sealing materials useful in building construction and by being paintable allow the color to be determined after installation rather than needing to select a pre-pigmented composition.
