Abstract: The present invention generally relates to processes for coating substrates, preferably metals, with solutions having fluoro-copolymers that comprise trans-1,3,3,3-tetrafluoropropene monomers and vinylidene difluoride monomers and at least 50 weight percent of the fluoro-copolymer comprises trans-1,3,3,3-tetrafluoropropene monomers. The fluoro-copolymer has a surface energy below about 40 mJ/m2. The surfaces of the substrates may be subjected to a phosphate treatment prior to application of the fluoro-copolymer coating, and/or the fluoro-copolymer coating may be applied directly onto the surface of the substrate.

Abstract: The invention provides polyurethane and polyisocyanurate foams and methods for the preparation thereof. More particularly, the invention relates to open-celled, polyurethane and polyisocyanurate foams and methods for their preparation. The foams are characterized by a fine uniform cell structure and little or no foam collapse. The foams are produced with a polyol premix composition which comprises a combination of a hydrohaloolefin blowing agent, a polyol, a silicone surfactant, and a sterically hindered amine catalyst.

Abstract: A method for treating process distillate heavies produced during uranium fluoride purification is described. The heavies contain primarily uranium hexafluoride, UF6, and molybdenum oxytetrafluoride, MoOF4. The uranium hexafluoride is removed via distillation at reduced pressure leaving essentially MoOF4 containing <0.1% of residual uranium hexafluoride. This mixture is hydrolyzed in water, then treated with a solution of sodium hydroxide until a pH of at least 7.5 is reached. The precipitated sodium diuranate and sodium fluoride are removed by filtration. The filtrate is reacted with calcium chloride to precipitate the molybdenum values as calcium molybdate containing trace quantities of calcium fluoride.
