<p>A latex composition is modified by the addition of an aromatic or an alkyl substituted aromatic polyisocyanate compound which unexpectedly has been found to result in improved properties such as increased drying rate and improved adhesion. The latex compositions generally contain a mineral filler therein such as calcium carbonate, various clays, and the like, as well as a frothing agent such as soaps for producing an aerated system. A particular use is in forming a coating on a primary carpet substrate.</p> |
