| titleOfInvention | Curable compositions of polysiloxanes and finely divided fillers and additive therefor |
| abstract | Abstract of the Disclosure The specification discloses a curable composition compri-sing 100 parts by weight of polysiloxane, 50 to 200 parts by weight of finely divided filler having an average particle size greater than 0.05 micron and not less than 0.5 parts by weight per 100 parts by weight of the filler of an additive which is a reaction product of an organic amine, or an oxide, hydroxide, carbonate, or bicarbonate or a mixture thereof with a sulphonic acid of the formula RSO3H in which R represents a hydrocarbon group which may have halogen or amino substituents and which contains not less than six carbon atoms. Preferred additives are reaction products of the sulphonic acid and an oxide, hydroxide, carbonate or bicarbonate of sodium, magnesium, zinc, calcium, barium, aluminium or a mixture thereof. The group R of the sulphonic acid may be R'C6H4 where R' represents an alkyl group having 6 to 18 carbon atoms and a preferred acid is dodecylbenzenesulphonic acid. The filler is preferably basic and may be oxide, hydroxide, carbonate or bicarbonate of calcium, magnesium, barium or zinc or a mixture thereof. Preferably the polysiloxane corresponds to a mixture and/or a reaction product of a polydiorganosiloxane HO(R"2SiO)XH with a compound containing silicon-bonded groups which are reactive therewith under the influence of moisture. The composition may be used to provide foamed or non-foamed, rigid or elastomeric products which may be employed, for example, as encapsulants, sealants or protective coatings. |
