Patent number: 5411804Abstract: The present invention relates to a heat resistant composition which exhibits excellent heat and wear resistances after being cured. Further, it has excellent releaseability and durability, and the cured film thereof has a more excellent stability than a prior art adhesive of this type, by preparing it from two components: a powder mixture consisting of 20% by weight or more of zirconium oxide, 1 to 10% by weight of sodium titanate, 2 to 15% by weight of yttria based on the zirconium oxide and the balance of silica; and a sodium silicate containing a small amount of water added thereto.Type: GrantFiled: August 4, 1993Date of Patent: May 2, 1995Assignee: Sugianikinzokukogyo Co. Ltd.Inventor: Nobuhiro Sugitani

Patent number: 5374303Abstract: A biodegradable oil and water emulsion release composition for facilitating the unmoulding of hydraulic bonding material comprises as the oil component an ester of a hindered polyhydric alcohol having no hydrogen atoms attached to any carbon atom in a beta-position to any hydroxyl group and a straight or branched chain, saturated or unsaturated C.sub.4 -C.sub.24 monocarboxylic acid. The ester may be partial and the partial ester may be alkoxylated. In a preferred embodiment also a straight or branched chain, saturated or unsaturated C.sub.8 -C.sub.24 monohydric alcohol is present. Also a method of unmoulding has been described.Type: GrantFiled: March 22, 1993Date of Patent: December 20, 1994Assignee: Unilever Patent Holdings B.V.Inventor: Bart van Hoorn

Patent number: 5366681Abstract: The present invention provides a release agent formed by reacting an organopolysiloxane compound having at least one hydrogen atom with a hydrocarbon compound having at least one double bond which reacts with said hydrogen atom and a manufacturing method thereof. The release agent of this invention, which makes substantially no migration into any pressure sensitive adhesive layer, is well adaptable to whichever process, extrusion laminating process or coating process.Type: GrantFiled: April 2, 1993Date of Patent: November 22, 1994Assignee: Goyo Paper Working Co., Ltd.Inventors: Shuzo Ohara, Ryoichi Kitamura

Patent number: 5350554Abstract: A method and apparatus for producing light-weight construction panels having a cementitious core layer surfaced with a layer of reinforcing fabric bonded to the two faces of the core includes the use of slurry applicator having a supporting member and a doctor in addition to a moving carrier for the slurry coated fabric. The edges of the panel also are covered with the fabric and may be open mesh edges. Cementitious slurry, for example, portland cement slurry, is applied to the fabric by means of a supporting member over which the fabric is drawn and a doctor means adjustably mounted above the supporting member. The supporting member is of a non-base-reactive material such as polypropylene or stainless steel; the use of such a supporting member permits better application of the slurry to the fabric before placement of the slurry coated fabric on the moving carrier.Type: GrantFiled: July 16, 1993Date of Patent: September 27, 1994Assignee: Glascrete, Inc.Inventor: Robert G. Miller
