Abstract
Versatile coalescing agents for water-borne coating applications are disclosed. The coalescents comprise propoxylated propylene glycol tert-butyl ether and one or more organic solvents, particularly glycol ethers. These coalescents efficiently reduce minimum film-forming temperature, and also have a dramatically reduced tendency to swell resins compared with prior art coalescents.
