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.

Silicone based emulsion, method for making same, and waterborne co-binder resin compositions comprising such emulsions

A process for preparing a rubber composition comprises:

Process for preparing rubber compositions and articles made therefrom

Compositions are provided which comprises an active hydrogen-containing resin, a flexibilizer and at least one curing agent. The cured compositions possess enhanced flexibility while maintaining hardness, and are highly suitable for applications such as coatings, adhesives, sealants, gaskets, industrial rubber goods, and the like.

Compositions with enhanced flexibility

There is provided a trisiloxane having a 3-(meth)acryloxy-substituted (hydroxylcyclohexyl)ethyl group, useful in making water absorbing silicone-hydrogel films for biomedical devices, such as contact lens, and a process for producing these monomers. This invention also provides for copolymers made from the trisiloxane having a 3-(meth)acryloxy-substituted (hydroxylcyclohexyl)ethyl group described herein.

(Meth)acryloxy-containing trisiloxane, siloxane-containing polymers and biomedical devices therefrom

A halo-functional silane possesses halogen functionality and alkanedioxysilyl functionality.

Halo-functional silane, process for its preparation, rubber composition containing same and articles manufactured therefrom

The invention is directed to an activated halo-containing aralkylsilanes possessing at least one hydrolyzable group bonded to a silicon atom and at least one halo functional group bonded to a carbon atom to which both the silicon atom and an aromatic group are covalently bonded. The invention is also directed to a process for making such a silane as well as its use in rubber compositions and articles containing such rubber compositions, such as tires.

Activated halo-containing aralkylsilane composition, process of preparing same and rubber compositions made therefrom

There is provided herein a rubber composition comprising (a) at least one rubber component; (b) at least one silane-reactive filler; (c) optionally, at least one activating agent and, (d) at least one silane of the general Formula (1):[XXXSi&#x2014;](G)[&#x2014;Y&#x2014;(CR-Z)]&#x2003;&#x2003;(1)wherein Xis selected hydrolyzable groups; Xand Xare independently hydrocarbons or selected hydrolyzable groups;
