Provided is a resin composition for surface treatment of a steel sheet including a binder resin, graphene and a solvent. More particularly, as only a small amount of the graphene is included in the resin composition used for surface treatment of a steel sheet, a user-required electrical conductivity can be provided to the steel sheet.

Provided is a non-crosslinked polyethylene composition for a power cable in which crosslinked polyethylene widely used in the world as an existing insulator for a power cable is replaced with a non-crosslinked polyethylene resin, and more particularly, a non-crosslinked polyethylene composition for a power cable having excellent processability, AC dielectric breakdown strength, space charge distribution, and water tree resistance.

An object of the present invention is to improve abrasion-resistance and spin performance of a golf ball having a polyurethane cover. The golf ball of the present invention is a golf ball having a core and a cover covering the core. The cover contains a layered silicate and a polyurethane resin having a secondary or a tertiary amine structure in a molecular chain thereof. In the present invention, the polyurethane resin used as a resin component constituting the cover has a secondary or tertiary amine structure in a molecular chain. Thus, it has a strong interaction with the layered silicate, and a reinforcing effect of the filler becomes even higher. As a result, abrasion-resistance and spin performance of the resultant cover are improved.
