Abstract
This invention pertains to neutralized silicone elastomer dispersions and methods for making neutralized silicone elastomer dispersions. This invention also pertains to compositions comprising the neutralized silicone elastomer and an acid reactive compound. The silicone elastomer dispersion are neutralized typically by blending the silicone elastomer dispersion with a base such as sodium bicarbonate or by adding a basic neutralizing agent to one or more of the raw materials used to make the silicone elastomer dispersion and removing the basic neutralizing agent by filtration or any other suitable means.
Claims16
A neutralized silicone elastomer dispersion produced by adding a 0.001 to 1 wt % of a basic neutralizing agent to the silicone elastomer dispersion.
A neutralized silicone elastomer dispersion produced by the method comprising reacting (A) a multi functional SiH containing polysiloxane and (B) C=C containing reactant in the presence of a platinum catalyst and in the presence of (C) a solvent, to produce a silicone elastomer dispersion, thereafter adding a 0.001 to 1 wt % of a basic neutralizing agent to silicone elastomer dispersion.
A neutralized silicone elastomer dispersion produced by the method comprising treating a SiH containing polysiloxane with a neutralizing agent;
- reacting (A) the neutralized SiH containing polysiloxane with (B) C=C containing reactant in the presence of a platinum catalyst and in the presence of (C) a solvent, to produce a silicone elastomer dispersion.
