Abstract
A UV and moisture-curable organopolysiloxane composition comprising (i) an organopolysiloxane terminated with a radical of formula (1): ##STR1## wherein R.sup.1 is a hydrogen atom or monovalent hydrocarbon radical, each of R.sup.2 and R.sup.3 is a divalent hydrocarbon radical which may contain a NH bond or ether bond, each of R.sup.4 and R.sup.5 is a monovalent hydrocarbon radical which may contain an ether bond, and a is equal to 0 or 1, (ii) a photo-polymerization initiator, and (iii) a curing catalyst. The composition readily cures either upon exposure to UV radiation or upon contact with moisture and from the surface to the deep interior within a short time, yielding cured products having satisfactory physical properties.
