  • Publication number: 20240262952
    Abstract: The present application relates to a resin composition or a use thereof. In the present application, it is possible to provide a resin composition or a cured body thereof that exhibits low adhesion force to a predetermined adherend while exhibiting high thermal conductivity. Also, in the present application, the low adhesion force can be achieved without using an adhesion force adjusting component such as a plasticizer or in a state where the use ratio thereof is minimized. The present application can also provide a product comprising the curable composition or the cured body thereof.

  • Patent number: 11628706
    Abstract: The present invention relates to a coolant heater comprising: a heating element for heating coolant; a first housing for accommodating the heating element; a cover plate for sealing the first housing in which the heating element is accommodated; a temperature fuse provided in an external space formed by coupling the first housing and the cover plate, and disposed to be adjacent to the cover plate; and a second housing for pressing the temperature fuse so as to pressurize the same toward the cover plate, wherein overheat sensing responsiveness of the heating element is improved such that the overheat of the heating element can be prevented, and failure factors in a part in which the temperature fuse is coupled are reduced such that a durability is improved.
