HEAT-HARDENING ELASTOMERIC ORGANOPOLYSILOXANE PASTES |
摘要 |
Pasty organopolysiloxane compositions having a penetration of from 80 to 400 and which can be thermoset into elastomers having good mechanical properties, are comprised of an intimate admixture of (i) 100 parts by weight of a diorganopolysiloxane oil having a viscosity of from 500 to 300,000 mPaxs at 25 DEG C., (ii) 7 to 85 parts by weight of reinforcing silicas having a specific surface area of at least 50 m2/g, said reinforcing silicas comprising from 55 to 95% precipitated silica and 5 to 45% pyrogenic silica, (iii) 1 to 20 parts by weight of a structuring inhibitor, and (iv) 0.1 to 4 parts by weight of an organic peroxide cross-linking agent. |
