POLYOLEFIN-BASED POWDER COATING COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a polyolefin-based powder coating composition giving a film excellent in adhesiveness and corrosion-control properties and having long term durability not only under normal conditions but also in the cases used for articles applied to water supplies especially for articles used under hot-water conditions such as hot-water supplying pipes. SOLUTION: The polyolefin-based powder coating composition is obtained by compounding 0.1-10 pts.wt. hydrotalcites in 100 pts.wt. polyolefin resin and forms a coating film excellent in corrosion-control properties under hot-water conditions, wherein the polyolefin resin comprises 100-5 wt.% denatured polypropylene and 0-95 wt.% native polypropylene.
