The process includes applying the curable composition to a supporting substrate to form a layer, partially curing the layer at a first temperature, engraving the partially cured layer, and then completing the curing by heating at a second temperature greater than the first temperature. The less than stoichiometric amount of the amine curing agent guarantees that after the first curing step, epoxy functionalities in the curable composition will be available for second curing step. The optional catalytic curing agent or latent curing agent promotes completion of the cure at higher temperature.Type: ApplicationFiled: March 5, 2014Publication date: September 11, 2014Applicant: E I DU PONT DE NEMOURS AND COMPANYInventors: Helen S.

Publication number: 20140231776Abstract: A method for producing a substrate having a concavity and convexity pattern includes: a step for applying a sol containing a silica precursor on a substrate to form a coating film; a step for drying the coating film; a pressing step for pressing a mold having a concavity and convexity pattern against the dried coating film with a pressing roll; a step for peeling off the mold from the coating film; and a step for baking the coating film to which the concavity and convexity pattern has been transferred. The coating film is dried in the drying step so that the ratio of weight of the coating film to dried weight of the coating film is in a range of 1.4 to 8.8, the dried weight being obtained by baking the coating film at a temperature of 100 degrees Celsius. The coating film may be heated in the pressing step.Type: ApplicationFiled: April 23, 2014Publication date: August 21, 2014Applicant: JX NIPPON OIL & ENERGY CORPORATIONInventors: Madoka TAKAHASHI, Yoshihiro KUMAGAI, Suzushi NISHIMURA

Patent number: 8778126Abstract: A method of producing a substrate suitable for artificial leathers. The substrate is composed of an entangled nonwoven fabric made of microfine fibers and a binder resin. At least one surface of the substrate is a densified layer which is made of the microfine fibers and which is substantially free from the binder resin. The binder resin is impregnated into a portion of the substrate other than the densified layer. The densified layer prevents the binder resin impregnated into the entangled nonwoven fabric from migrating into the surface of the entangled nonwoven fabric, thereby providing the substrate having the surface substantially free from the binder resin. The peeling strength between the substrate and a grain layer formed on the surface thereof is drastically improved because the surface of the substrate is substantially free from the binder resin.Type: GrantFiled: November 2, 2012Date of Patent: July 15, 2014Assignee: Kuraray Co., Ltd.Inventors: Michinori Fujisawa, Jiro Tanaka, Yoshiyuki Ando, Norio Makiyama

Publication number: 20140186693Abstract: A lithium ion (Li-ion) battery module includes a container with one or more partitions that define compartments within the container. Each of the compartments is configured to receive and hold a prismatic Li-ion electrochemical cell element and electrolyte. The Li-ion battery module also includes a cover configured to be disposed over the container to close the compartments. The container includes an electrically nonconductive polymeric material (e.g., plastic) with a nanomaterial applied to the polymeric material. The nanomaterial enhances the impermeability of the container to reduce ingress of moisture into the compartments and to reduce egress of the electrolyte from the compartments.Type: ApplicationFiled: December 27, 2013Publication date: July 3, 2014Applicant: Johnson Controls Technology CompanyInventors: Matthew R.
