Abstract
A curable composition for use as a sealant, in which the curable composition comprises a silicone fluid in an amount from about 80 wt % to about 90 wt %, a vinyl group containing polyorganosiloxane in an amount from about 10 wt % to about 20 wt %, a hydrogen containing polysiloxane in an amount from about 0.5 wt % to about 2.0 wt %, and a hydrosilation photocatalyst in an amount from about 5 ppm to about 100 ppm. The sealant cures in about 1 second to about 20 seconds during reaction of the vinyl group containing polydiorganosiloxane and the hydrogen containing polysiloxane, by exposure to ultraviolet radiation, in the presence of the hydrosilation photocatalyst. The sealant has an adhesion force to plastic from about 2.0 N/100 mm to about 4.0 N/100 mm.
