A high silica glass composition comprising about 92 to about 99.9999 wt. % SiO_(2 )and from about 0.0001 to about 8 wt. % of at least one dopant selected from Al_(2)O_(3), CeO_(2), TiO_(2), La_(2)O_(3), Y_(2)O_(3), Nd_(2)O_(3), other rare earth oxides, and mixtures of two or more thereof. The glass composition has a working point temperature ranging from 600 to 2,000 C. These compositions exhibit stability similar to pure fused quartz, but have a moderate working temperature to enable cost effective fabrication of pharmaceutical packages. The glass is particularly useful as a packaging material for pharmaceutical applications, such as, for example pre-filled syringes, ampoules and vials.


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.
