ZINC POWDER CAPABLE OF BEING DISPERSED IN WATER AND ZINC POWDER-CONTAINING AQUEOUS COATING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a zinc powder that can be stably dispersed in water for a long period of time without using a hexavalent chromium at all and to provide a zinc powder-containing aqueous coating material. SOLUTION: The zinc powder capable of being dispersed in water is formed by incorporating a zinc powder and a silane coupling agent having a mercapto group in its molecule in an amount of 0.1-10 pts.wt. based on 100 pts.wt. zinc powder. The aqueous coating material is constituted by using the zinc powder. COPYRIGHT: (C)2004,JPO
