ABSTRACT:
Vibration dampening hydrosilation cured silicone formulations which cure at room temperature and, after a subsequent heat cure cycle, provide good primerless adhesion to aluminum and titanium substrates and improved adhesion to polymeric composite materials such as polyimide/glass fiber composite materials. The composition includes (a) a polyorganosiloxane having plural alkenyl groups thereon; (b) a polyorganosiloxane having plural silicon hydride groups thereon; (c) a hydrosilation catalyst, and (d) a combination of adhesion promoter compounds including at least one silane adhesion promoter compound; triallyl isocyanurate; and diallyl maleate. Still further improvements to polyimide substrates are provided when a primer is employed or the substrate is treated by a very brief exposure to a flame or to UV irradiation.
