摘要
A thermal treatment method for insulating glass units or IGUs having one or more suspended polymer films includes first curing a sealant at a first elevated temperature for a specified duration, then shrinking the suspended film at a second, higher, elevated temperature for a specified duration, and then cooling the IGUs back to ambient temperature. The various heating and cooling stages may be performed in a tunnel oven having different length sections at the desired temperatures, while the IGUs are conveyed from one section to the next.
