Continuous coatings are prepared using novel two part compositions and
methods. The two part compositions of the invention comprise, in separate
containers, a powder polymer composition and a coalescing agent. The
powder composition has preferred particle size distribution and
composition for use in the compositions or methods of the invention. The
coalescing agents of the invention cooperate with the powder part to
result in a excellent finish having the appropriate drying hardness,
durability, etc. The novel method of the invention involves contacting a
coalescing agent with polymer particles in a variety of coating methods.
The particles and the coalescing agent interact to form a continuous
coating layer or finish layer. The basic coating formation methods of the
invention can be embodied in a number of methods or protocols including
applying a solid polymer to the liquid coalescing agent, applying the
agent to the polymer particulate or applying the liquid and polymer
simultaneously. In any protocol, a desirable floor finish can be easily
formed. This invention is particularly suitable for a floor finish
composition.
