Foamable waterborne dispersions which form stable flexible foams under ambient cure conditions are disclosed, said foamable waterborne dispersions comprising: a polyurethane polymer formed from one or more aliphatic or cycloaliphatic polyisocyanate and at least two different polymeric polyol components selected from polyether polyol, polyester polyol, and polycarbonate polyol; wherein the ambient cure conditions include a temperature of from 4&#xb0; C. to 32&#xb0; C., and a humidity of 0% relative humidity to 90% relative humidity. Also disclosed are the flexible foams produced from the foamable waterborne dispersions, as well as methods of providing a space filling layer or space filling volume adjacent to or on a surface, said methods comprising applying to said surface a foamed sample of the foamable waterborne dispersions, and allowing the foamed sample of foamable waterborne dispersion to dry under ambient conditions to yield a stable flexible foam.

A composition for forming a foamed silicone elastomer is disclosed. The composition comprises: A) an organopolysiloxane having at least two silicon-bonded ethylenically unsaturated groups per molecule; B) an organohydrogensiloxane having at least two silicon-bonded hydrogen atoms per molecule; C) a hydrosilylation catalyst; D) a chemical blowing agent; and E) a physical blowing agent. The hydrosilylation catalyst C) is present in a catalytically effective amount. The chemical blowing agent D) has at least one hydroxyl (OH) group, and is present in an amount to provide a OH content &#x3e;0 and &#x3c;500 parts per million (ppm). The physical blowing agent E) undergoes a phase change from a liquid to a gaseous state during exposure to atmospheric pressure and a temperature &#x2265;0&#xb0; C. The blowing agents D) and E) are different from one another. A foamed silicone elastomer, and methods of forming the composition and foamed silicone elastomer are also disclosed.

Compounds described herein inhibit biofilm formation or disperse pre-formed biofilms of Gram-negative bacteria. Biofilm-inhibitory compounds can be encapsulated or contained in a polymer matrix for controlled release. Coatings, films, multilayer films, hydrogels, microspheres and nanospheres as well as pharmaceutical compositions and disinfecting compositions containing biofilm-inhibitory compounds are also provided. Methods for inhibiting formation of biofilms or dispersing already formed biofilms are provided. Methods for treating infections of gram-negative bacteria which form biofilms, particularly those ofand more particularly

The present invention provides aqueous, epoxy-based sizing compositions for carbon fibers. The size composition incorporates highly functionalized film forming epoxy novolac phenolic resins in combination with highly functionalized sulfonated polyesters having high Tg characteristics, sulfonate equivalent weights in the range from 2000 to 20,000 and number average molecular weights in the range from about 1000 to about 100,000. The present invention also provides corresponding sized carbon fibers and fiber-reinforced matrices.
