Abstract
A curable silicone composition comprising an addition reaction product of an organopolysiloxane having amino groups at both ends of its molecule and a vinyl group-containing isocyanate, and a moisture-curing or anaerobic-curing catalyst and a photopolymerization catalyst. The silicone composition has high photocurability and moisture- or anaerobic-curability, easy to manufacture and easy to handle.
Claims2
A curable silicone composition comprising a reaction product of an organopolysiloxane represented by the general formula:
- ##STR6## where R.sup.1 is alkylene having 1 to 6 carbon atoms;
- R.sup.2 is alkyl, vinyl, allyl, benzyl or alkyl substituted with halogen;
- R.sup.3 is alkyl, vinyl, allyl, benzyl, ##STR7## or any of the above substituted with halogen;
- X is hydroxyl or a hydrolyzable group;
- 1 is zero or 1;
- m is an integer of 10 to 10,000;
- and a is zero to 2, and a vinyl group-containing isocyanate;
- a moisture-curing or an anaerobic-curing catalyst and a photopolymerization catalyst.
