Abstract
An MQ resin including at least 30% SiO, preferably at least 50 wt % SiO, and having dynamic viscosity of 50 centipoises (cps) to 750 cps at 25° C. is produced from a stable ethylsilicate polymer. The ethylsilicate polymer includes not greater than 1 wt % of TEOS monomer. The ethylsilicate polymer is produced by a two step addition of catalysts wherein a hydrolysis catalyst, for example, hydrochloric acid is added initially and a second catalyst, such as phosphonitrilic chloride trimer, is added subsequently.
