Coating composition containing tetrapod-like zinc oxide whiskers

摘要

The present invention relates to a coating composition characterizing by including tetrapod-like zinc oxide whiskers each comprising a central nuclear portion from which 4 crystalline needles are outwardly extended each in different direction, average diameter of said needle measured at the foot portion being 0.7 to 14 mu m and average length of said needle being 3 to 200 mu m. Various coating compositions being excellent in chipping resistance, abrasion resistance, or road marking properties, or abrasive putty properties are provided, as well as curing acceleration catalyst using the present whiskers as a carrier material.
