Abstract
The present invention is directed to silicone formulations which are capable of being rapidly cured to tough elastomeric materials through exposure to UV radiation. The cured products demonstrate high resistance to flammability and combustibility.
Claims16
A flame-resistant silicone composition curable by UV irradiation to an elastomer comprising:
- (a) a reactive silicone resin component comprising a reactive polyorganosiloxane having at least one carboxylate-containing functional group
- (b) optionally, an inorganic filler component;
- (c) a photoinitiator component;
- and
- (d) a flame-retardant component in an amount effective to enhance the resistance of said composition to flammability, wherein the flame-retardant component is the combination of hydrated alumina and a member selected from the group consisting of organo ligand complexes of transition metals, organosiloxane ligand complexes of transition metals, and combinations thereof.
