Patent number: 9157005Abstract: The method of foaming and applying a sealing material is characterized by comprising the steps of hot-melting the sealing material; mixing nitrogen gas into the melted sealing material under a predefined pressurization; discharging the resultant mixture at a predefined pressure into the air to thus foam the mixture and simultaneously apply it to a place necessary to seal, thus making a sealing foam; and curing this sealing foam by ultraviolet rays. By this method, the sealing material does not involve flowing after applied, and shows an excellent sealing performance even under severe heat resistance conditions, and also can make good independent cells inside even when used in a foamed condition.Type: GrantFiled: January 15, 2014Date of Patent: October 13, 2015Assignee: NITTA GELATIN INC.Inventors: Kazuyoshi Sekita, Hiroyuki Nakatani, Seiki Ueno
