    摘要： The invention relates to organopolysiloxane compositions which are stable when stored under anhydrous conditions, but when exposed to moisture cure to an elastomer containing (a) a diorganopolysiloxane having terminal condensable groups, (b) a silicon compound having 3 amino groups bonded to silicon via nitrogen and/or oxime groups bonded to silicon via oxygen per molecule and (c) a silicon compound having at least one thiol group selected from mercapto-functional silanes or siloxanes. The presence of the mercapto-functional silanes or siloxanes substantially retards the formation of skin but does not substantially extend the cure time of the organopolysiloxanes compositions. These compositions are useful in, for example, screen printing, where a long skin-over time is desired.

    摘要： This invention relates to silanes of the general formulaR.sub.n Si(OCR.sub.2.sup.1 COZR).sub.4-nwhere R represents the same or different monovalent hydrocarbon radicals or substituted monovalent hydrocarbon radicals, R.sup.1 is hydrogen or the same as R, Z is oxygen or the group ##STR1## where R.sup.1 is the same as above, n is 0 or 1 and oligomers thereof. These silanes are prepared by reacting silanes of the general formulaR.sub.n SiX.sub.4-nwhere R and n are the same as above and X represents the same or different hydrolyzable atoms or condensable groups other than RCOCR.sub.2.sup.1 CO groups, with alpha-hydroxycarboxylic acid esters or amides. The silanes, which have at least three condensable groups per molecule, may be mixed with a diorganopolysiloxane containing terminal condensable groups and at least one additional substance to prepare compositions which are storage-stable under anhydrous conditions, but crosslink when exposed to moisture at room temperature to form elastomers.
