ABSTRACT:
A method for masking selected areas of a glass, glass-ceramic, or ceramic surface against subsequently-applied coating compositions. The method contemplates three general steps: (a) a molten thermoplastic masking coating consisting essentially of about 10-60% bentonite clay, 0-40% of a refractory metal oxide, and 40-80% of a thermoplastic organic medium is applied from a heated surface onto the surface of an elastomeric or silicone-coated body; (b) the thermoplastic coating is cooled thereon to a temperature at which the coating exhibits sufficient tack and cohesiveness to permit transfer from the elastomeric or silicone-coated body; and (c) the so-coated body is brought into contact with the surface of a glass, glass-ceramic, or ceramic article to transfer the coating thereto.
