摘要

Water-based coating or caulking compositions especially for exterior surfaces or seams which upon application quickly develop resistance to being washed out by rain comprise an aqueous dispersion of water-insoluble latex polymer prepared by emulsion polymerization, pigment dispersed with anionic polymer, and water-soluble salt of multivalent complex ion having ligands selected from ammonia or organic amine, and have a total solids content of from 50% to 90% by weight. Those compositions having a pigment to binder ratio of 1:1 to 3:1 are particularly useful as roof mastics.
