Abstract
The present invention relates to paint extenders or open-time extenders, which are mixed with an architectural coating, such as aqueous latex paints, to increase the coating's open time. The open-time extender comprises acrylic or vinyl latex particles having a mean diameter of less than about 150 nm, and at least one crosslinkable monomer that can crosslink the latex particles in the open-time extender to the latex particles in the architectural coating at ambient conditions. The open-time extender also comprises water and the total solid content of the open-time extender is less than about 15% by weight.
