Organopolysiloxane (a) having two or more silicon-bonded hydroxyls or hydrolyzable groups,n n n Silanes of formula G 2 -Si-R 1 2 (b), wherein group G can each react with hydroxyl or hydrolyzable groups in (a), and R 1 is each an alkyl group having 1 to 10 carbon atoms, al Kenyl group, alkynyl group, aryl group or fluorinated alkyl group], at least one filler (c) and a photocatalyst (d). It is preferred that at least one R 1 group is unsaturated, but otherwise it is an additional component in the form of an unsaturated compound selected from the group consisting of unsaturated short chain siloxanes, unsaturated cyclic siloxanes, unsaturated fatty acids, unsaturated fatty alcohols and unsaturated fatty acid esters (e ) Is further included. The cured product is generally used as a sealant to prevent contaminant adhesion after curing and to have a protective layer over the airtight interface.n n n Organopolysiloxane, sealant, photocatalyst, coefficient of friction, gloss value. |
