A component of a flow machine or of a compressor has the coating composition. A method of maintaining a flow machine or a compressor uses the coating composition.
Abstract:
A resin composition is provided. The resin composition comprises an epoxy resin, a zinc oxide powder and a hardener, wherein the zinc oxide powder has a Mohs hardness ranging from about 4 to about 5 and a diameter ranging from about 0.1 μm to about 50 μm, and the amount of the zinc oxide powder is more than 0.5 parts by weight and less than 10 parts by weight per 100 parts by weight of the epoxy resin.
Abstract:
A liquid crystal polyester resin composition for camera modules is used, the composition including, based on 100 parts by mass of the composition as a whole, (A) 49.5 to 69.5 parts by mass of a liquid crystal polyester, (B) 30.0 to 50.0 parts by mass of an irregular form or spherical powder having a Mohs hardness of 5 or higher and a primary particle diameter of 5 μm or less, and (C) 0.5 to 5.0 parts by mass of carbon black. The use of the resin composition allows a reduction in the amount of dust generated (particles falling off) during the production of the camera, the use of the camera, and the operation of the camera modules. The resin composition has high surface hardness, is excellent in balance between heat resistance, stiffness, moldability, and resistance to falling of particles off a surface, and causes no malfunction during autofocus control.

Abstract:
A method for improving joint strength between a first and second member comprising the steps of: applying a sealant material including a matrix material at least partially encasing rigid components to the first and second members; joining the first and second members upon an application of force that is applied through the use of one or more fasteners; wherein a compressive force is applied to the exterior surface of both the first and second members by the one or more fasteners while the rigid components apply an internal tension force acting opposite of the compression force to the interior surface of both the first and second members proximate to the fastener to form a mechanical lock thereby reducing slippage and generally maintaining the joint in position.
