Continuous coatings can be 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 sold 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.
A method of forming a coating layer on a substrate, the coating layer comprising a unitary layer having a thickness of about 1 to about 20 microns, the method comprising:
A two part coating composition, resulting in a unitary coating layer having a thickness of about 1 to about 20 microns, the composition comprising, in separate containers:
A method of forming a coating layer on a floor surface, the finish layer comprising a unitary layer having a thickness of about 1 to about 20 microns, the method comprising:
A floor coating comprising a single layer having a thickness of about 2 to 12 microns, the coating comprising a continuous polymer layer having an entrapped residue in the coating the residue comprising a coalescing agent with a VOC of less than 10 mm-Hg, the residue substantially free of an aqueous or solvent medium.
A method of forming a coating layer on a flooring unit used in forming a floor surface, the coating layer comprising a unitary layer having a thickness of about 3 to about 12 microns, the method comprising:
