Document Type and Number:
Japanese Patent JP4907752
Kind Code:
B2
Abstract:
A method of thickening organic solvents and silicone fluids with elastomers involves reacting (A) an IDENTICAL Si-H containing polysiloxane with (B) an alkene such as alpha, omega-diene; conducting the reaction in the presence of (C) a platinum catalyst and (D) a solvent; continuing the reaction until an elastomer is formed by crosslinking and addition of IDENTICAL Si-H across double bonds in the alpha, omega-diene; adding additional solvent and a post cure quenching agent (E) to said elastomer; and subjecting the solvent, post cure quenching agent and elastomer to shear force until a paste is formed. The post cure quenching agent used herein is selected from (i) a strong platinum complexing ligand, (ii) a IDENTICAL SiH quencher such as vinylsiloxane or (iii) an unsaturated organic compound.
