A stand-off is necessary to separate two glass lites (panes of glass) in a vacuum insulated glazing system. This stand-off must provide sufficient mechanical support to keep the lites apart despite one atmosphere pressure pushing the lites together. For systems that are designed with flexible edge seals, there will be movement of one lite relative to the other during diurnal cycling, and the stand-offs will therefore be scraped against at least one of the lite surfaces. Because many mechanically robust materials suitable for stand-offs have high friction, it is beneficial to apply a lubricant to the surface of the stand-off. However, it is also beneficial to adhere the stand-off to one lite during the manufacturing operation, and this need opposes the need for good lubricity. This invention describes means for optimizing the composition of a stand-off to meet these conflicting needs.
