Abstract:
A stable MQ resin solution with over 50% SiO2 and having viscosity of 50 cps at 25° C. to about 750 cps at 25° C. and which is essential free of monomer is disclosed. The stable resin solution is made by a two step addition of catalysts wherein a hydrolysis catalysts, as for example, hydrochloric acid is added initially and a second catalysts such as Phosphonitrilic chloride trimer is added subsequently.
