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.

摘要： Siloxane foams which are activated and cured by heating can be prepared by mixing an organohydrogensiloxane, a hydroxylated organosiloxane and a rhodium catalyst in amounts such that the ratio of silicon-bonded hydrogen atoms to silicon-bonded hydroxyl radicals is from 2.5 to 40 and thereafter heating the mixture above 90.degree. C. The rhodium catalyst provided a pot life of at least 8 hours when used in amounts of 0.0025 grams per 100 grams of hydroxylated organosiloxane. The siloxane foams can be made to have an increased fire retardant property by adding 0.01 to 2 parts by weight carbon black based on the weight of the total composition. Siloxane foams are also prepared from mixing an organohydrogensiloxane, a hydroxylated organosiloxane, a vinyl containing triorganosiloxy endblocked polydiorganosiloxane and a rhodium catalyst. These foams can be used for cushioning, in acoustical applications and protective filling or coating applications and especially applications wherein fire retarding is important.

摘要： Siloxane foams can be prepared by mixing an organohydrogensiloxane, a hydroxylated organosiloxane and a platinum catalyst in amounts such that the ratio of silicon-bonded hydrogen atoms to silicon-bonded hydroxyl radicals is from 2.5 to 7 and thereafter allowing the mixture to foam. The amount of open-cell structure in the foam can be increased by having present in the mixture an organomonohydrogensiloxane such that the molar ratio of silicon-bonded hydrogen atoms from the organohydrogensiloxane to silicon-bonded hydrogen atoms from the organomonohydrogensiloxane is from 0.4 to 2. The siloxane foams can be made to have an increased fire retardant property by adding 0.01 to 2 parts by weight carbon black based on the weight of the total composition. Siloxane foams are also prepared from mixing an organohydrogensiloxane, an organomonohydrogensiloxane, a hydroxylated organosiloxane, a vinyl containing triorganosiloxy endblocked polydiorganosiloxane and a platinum catalyst.
