Claims
- 1. An addition cross-linking molding or lining compound based on silicones consisting essentially of
- (a) an organo polysiloxane containing two or more vinyl reactive end groups,
- (b) a catalyst comprising a platinum complex prepared from hexachloroplatinic - (IV) acid,
- (c) a filler,
- (d) an isoparaffin having 8 to 24 carbon atoms and
- (e) a cross-linking agent comprising a organohydrogen polysiloxane.
- 2. A compound according to claim 1, wherein said isoparaffin is selected from the group consisting of isohexadecane, isoeicosane and mixtures thereof.
- 3. A compound according to claim 1, wherein the isoparaffin is contained in an amount of 1 to 50% by weight.
- 4. A compound according to claim 1, wherein the isoparaffin is contained in an amount of 5 to 30% by weight.
- 5. A compound according to claim 1, wherein the organopolysiloxane is a silicone oil which is a vinyl-end-stopped polydimethyl siloxane having a viscosity of 500 to 5,000,000 mPa.s at 20.degree. C.
- 6. A compound according to claim 1, wherein the filler is selected from the group consisting of powdered quartz, crystobalite, calcium sulphate, diatomaceous earth, talcum, calcium carbonate and precipitated and pyrogenically prepared silicone dioxide.
- 7. A compound according to claim 1, wherein a two-paste system is utilized, said two-paste system comprising a first paste which comprises a first portion of the organopolysiloxane, a first portion of said isoparaffin, said cross-linking agent and a first portion of the filler and a second paste which comprises a second portion of the organipolysiloxane, a second portion of said isoparaffin, a second portion of the filler and said catalyst.
- 8. A compound according to claim 7, wherein the ratio of the two pastes if 1:1 by weight.
- 9. A compound according to claim 7, wherein the ratio of the first paste to the second paste is 9:1 by weight.
- 10. A compound according to claim 7, wherein the organopolysiloxane is a silicone oil.
- 11. A condensation cross-linking molding or lining compound based on silicones consisting essentially of
- (a) an organo polysiloxane comprising two or more reactive hydroxyl reactive end groups,
- (b) a catalyst comprising a liquid or pasty curing component comprising a metal salt of a monocarboxylic acid ester,
- (c) a silicic acid ester cross-linking agent,
- (d) a filler and
- (e) an isoparaffin having 8 to 24 carbon atoms.
- 12. A compound according to claim 11, wherein said isoparaffin is selected from the group consisting of isohexadecane, isoeicosane and mixtures thereof.
- 13. A compound according to claim 11, wherein the isoparaffin is contained in an amount of 1 to 50% by weight.
- 14. A compound according to claim 11, wherein the isoparaffin is contained in an amount of 5 to 30% by weight.
- 15. A compound according to claim 11, wherein the filler is selected from the group consisting of powdered quartz, crystobalite, calcium sulphate, diatomaceous earth, talcum, calicum carbonate and precipitated and pyrogenically prepared silicone dioxide.
