摘要:
A coating composition is provided, the starting materials of which comprise nano SiO2, film-forming substance, film-forming aid, accelerator, acid, and water. The composition has pH of 3-9. A passivated zinc-plated material is also provided. The zinc-plated material comprises zinc-plated substrate and passivated coat adhered to the surface of the zinc-plated substrate, wherein the passivated coat is formed by curing the coating composition. The coating composition can impart to the zinc-plated material excellent corrosion resistance, water resistance, high temperature resistance, surface conductivity, and adhesion to the zinc-plated substrate. Additionally, the coating composition contains no Cr6+, and satisfies the requirement of EU RoHS Directive.

摘要:
A golf bag comprises a bag body. A club protection cover capable of axially sliding along a golf bag mouth is disposed in the golf bag mouth at an upper end of the bag body. A slide mechanism is disposed inside the club protection cover. The club protection cover is connected in the golf bag mouth through the slide mechanism. The golf bag can prevent damage to the club, and extend the service life of the club.
