Abstract
PURPOSE: To prevent blocking inexpensively and effectively by coating a prescribed aqueous dispersion contg. an extender pigment and a surfactant on a bitumen-type vibrationproof sheet.
CONSTITUTION: An aqueous dispersion of ≤50% solids, more preferably ≤20% prepd. by adding and compounding 0.1W10pts.wt. a surfactent to 100pts.wt. an extender pigment, for example, calcium carbonate powder etc. is coated on a bitumen-type vibrationproof sheet, after which it is dried.
