COATINGS FOR REDUCING COEFFICIENT OF FRICTION ON GLASS/METAL WORKING SURFACES OF GLASS FORMING MACHINES

摘要

The use of a ceramic based composition is disclosed for reducing frictional forces between moving molten glass and working surfaces of a glass forming machine. The ceramic based composition is applied as a dispersion and cured on the working surfaces, such as the blank cavity of a glass container mold. The preferred ceramic based composition is sold under the trademark "XYLAR" and has been found to be particularly effective in reducing frictional engagement over extended periods of time in the operation of glass forming machines.
