Method of reducing the foam density of silicone foams and compositions |
摘要 |
Mixing a fluorinated surfactant with a silicone foam composition decreases the density of the cured foam. Increasing the amount of fluorinated surfactant decreases the foam density. Silicone compositions comprising a hydroxylated organosiloxane, an organohydrogensiloxane, a platinum catalyst and a fluorinated surfactant cure to foams with lower densities than the same compositions without the fluorinated surfactant. The cured foams can be used in the same applications as other silicone foams.
