20090220799 | Method Of Making Multilayer Structures Using Tapes On Non-Densifying Substrates - A method of applying a ceramic coating to a substrate comprises laminating one or more layers of a green ceramic tape to a rigid substrate using a tackifying resin to adhere the tape to the substrate. Upon firing, the tackifying resin ensures near zero shrinkage of the tape in the XY plane without usage of elevated pressures or temperatures during lamination of green tape to the substrate. The thermal degradation completion temperature of the tackifying resin is lower than that of the resin binder used in the green tape. | 09-03-2009 |
