  • Silicone oils and solvents thickened by silicone elastomers
    Patent number: 5654362
    Abstract: Silicone gels are made by reacting an .tbd.Si--H containing polysiloxane with an alpha, omega-diene. The reaction is conducted in the presence of a platinum catalyst and in the presence of a low molecular weight silicone oil. The reaction is continued until a gel is formed by crosslinking and addition of .tbd.Si--H across double bonds in the alpha, omega-diene. The silicone gel can then be crumbled into a silicone powder using mechanical force. When additional amounts of low molecular weight silicone oil are added to the gel, and the silicone oil and the gel are subjected to shear force, a silicone paste can be formed.
