A mold release composition is provided contains a minimum of three reactive moieties per molecule to provide for both mold adhesion and crosslink density. The composition is soluble in a VOC-free organic solvent or water, alone or with resort to an emulsifier. The composition can be used as a semi-permanent mold release in some embodiments. 2. The composition of claim 1 , further comprising at least one emulsifier suitable for producing an emulsion of said polysiloxane claim 1 , water claim 1 , catalysts claim 1 , antimicrobial agents claim 1 , fillers claim 1 , pigments claim 1 , wetting agents claim 1 , cross-linking agents claim 1 , or combinations thereof.3. The composition of wherein said reactive moieties include at least three reactive moieties.4. The composition of wherein said reactive moieties are all pendant.5. The composition of wherein each of said reactive moieties is independently one of the glycydoxy claim 1 , the C-Calkoxy claim 1 , the halogen claim 1 , the amine claim 1 , the isocyanate claim 1 , the ureido claim 1 , the ethylenically unsaturated group claim 1 , the methylacryloxy claim 1 , the acryloxy claim 1 , the mercapto claim 1 , the vinyl claim 1 , the styryl claim 1 , the C-Chalo alkyl claim 1 , the acrylic claim 1 , the allyl alcohol claim 1 , the halogen claim 1 , and the hydroxyl group.6. The composition of wherein all of said reactive moieties are like moieties.7. The composition of further comprising a VOC-free solvent.8. The composition of wherein said solvent is water.9. The composition of wherein the mold surface is a bladder surface.10. A process of molding comprising:{'claim-ref': {'@idref': 'CLM-00001', 'claim 1'}, 'applying a composition of to a mold surface;'}curing said composition to form a mold release coating; andplacing of a material into contact with said mold release coating to form an article; andremoving the article from contact with said mold release coating.11. The process of wherein the mold surface is a bladder ...
