Room temperature-curable organopolysiloxane composition containing a photosensitizer

Abstract From the Canadian patent

Abstract Room temperature-curable organopolysiloxane compositions are made from essentially linear organopolysiloxanes having hydroxyl or hydrolyzable end groups a cross-, linking agent, a filler, optionally a curing catalyst an, unsaturated ester having at least ten carbon atoms in the unsaturated fatty acid component of the ester and a photo, sensitizer. These compositions cure to elastomeric materials which do not soil on the surface or the surrounding areas of the substrate in contact with the cure product. The adhesion of these cured products is not reduced.
