A magnetic powder for bonded magnets is obtained by subjecting starting magnetic particles to agitation in a high speed air stream whereby individual particles are mechanically impacted with one another by the action of the stream. A magnetic composition comprising the magnetic powder and a resin binder is also described wherein the magnetic powder can be highly packed in the resin binder to ensure good fluidity of the composition. The magnetic composition can be prepared by mixing magnetic particles and a resin binder powder, subjecting the mixture to agitation in a high speed air stream for impactness of the particles and heading the mixture or by subjecting magnetic particles to agitation in a high speed air stream, mixing the agitated particles with a powder of a resin binder and heading the resultant mixture.

Magnetic powder for bonded magnets, composition for bonded magnets and

A waterproof nut which may be used, for example, inside a water storage tank, is constituted by a metallic nut body having the outer periphery coated with a synthetic resin layer which also covers both the front and rear surfaces of the nut body. The resin layer which covers the rear surface of the nut body includes a cap-shaped portion for accommodating the free end of a bolt which is screwed into the nut body in such a manner that the free end projects from the rear surface of the nut body, whereby water is prevented from entering the nut body.

A sealant composition for the puncture-sealing tire and a method of producing the same are disclosed. This sealant composition is crosslinking-reaction type and comprises (A) at least one rubber, (B) a tackifier, (C) an acryloyl or methacryloyl group-containing polymerizable unsaturated compound, (D) a filler and (E) a photopolymerization initiator. In the production of the sealant composition, the component (A) is first reacted with the component (C) and then kneaded with the components (B), (D) and (E).
