Organosilicone pastes and greases including at least one oily diorganopolysiloxane polymer with a dynamic viscosity at 25 degree C of at least 500 mPa.s, and at least one alkali-metal or alkaline-earth metal carbonate, but no actual thixotropic agent, wherein said carbonate has a particle size of at most 0.5 'mu'm and a high BET specific surface area of more than 5 m2/g, and is present in an amount of at least 20 wt percent based on the total composition. The preparation method is carried out at a low temperature, e.g. 5-40 degree C. |
