  • Patent number: 11104811
    Abstract: Aqueous intumescent coating compositions which include a non-ionic surfactant having a hydrophilic-lipophilic balance (HLB) of 9 to 20, and substrates coated with the coating composition are disclosed. Inclusion of the non-ionic surfactant in the coating compositions is found to reduce char cracking and improve the mechanical strength, cell size, and cell density for intumescent chars formed when coatings deposited from the coating compositions are exposed to open flame and/or elevated temperatures, as compared to the same coatings lacking the non-ionic surfactants.

  • Patent number: 9546326
    Abstract: The present invention is directed to methods of separating a fluid emulsion stream into a hydrocarbon stream and an aqueous stream, by contacting the stream with a microporous membrane to yield a hydrocarbon product stream and an aqueous product stream. The membrane comprises a substantially hydrophobic, polymeric matrix, and substantially hydrophilic, finely divided, particulate, substantially water-insoluble filler distributed throughout the matrix. The polymeric matrix has a mean pore size less than 1.0 micron, and the purities of the product streams are independent of the flux rate of the aqueous product stream and the pore size of the membrane.
