Abstract
A vibration damping coating is disclosed for use on cars, interior trims, construction materials, home electric appliances, etc. where damping of vibratory energy is desired. The coating contains in its base material mica flakes and calcium carbonate in a combined amount of 30-70% by weight. The weight proportion of the mica flakes and the calcium carbonate is 75/25-0/100. The vibration damping coating provides an excellent vibration damping property and will not crack or peel when used on a curbed surface.
