Abstract
A crosslinkable silicone based emulsion composition includes a hydroxylated polydiorganopolysiloxane grafted onto at least one colloidal silica dispersion, wherein the at least one hydroxylated polydiorganopolysiloxane grafted onto the least one colloidal silica dispersion contains residual silanol groups from the at least one hydroxylated polydiorganopolysiloxane. Further, a waterborne co-binder silicone-organic resin composition includes (A) the crosslinkable silicone emulsion and (B) an organic resin emulsion which provides improved cured properties including, but not limited to, improved hydrophobicity (water resistance), scratch resistance and gloss retention as well as process for making the emulsions and the compositions.
