ABSTRACT:
Pyrene based fluorescent organopolysiloxanes which bear two or more reactive silicon-bonded sites are useful as durable markers and indicators of the degree of cure in curable silicone compositions. Having more than one reactive site the compounds participate in the curing reaction of the curable composition and thus do not adversely affect its curing behavior. The resulting fluorescent curable compositions are particularly useful in the preparation of adhesive-release coatings.
