..., such as those using encapsulated film adhesive to check for part fit-up prior to bonding, can also serve as effective drying cycles for thin sections. In addition, storage of dried details in a temperature-and humidity-controlled lay-up room can extend the time between drying and curing. Numerous surface...

If this condition exists only partially—that is, if part of the load is carried by the fluid pressure and the rest is borne by contacting asperities separated by a molecularly thin lubricant film—the term thin-film lubrication is used. In the most severe form of thin-film lubrication, the entire load is carried...
