Abstract
Vacuum insulating glass (VIG) units, edge seals for VIG units and methods for forming the edge seals are provided. The VIG units include an edge seal that includes a viscous material, which serves to restrict the rate at which gas permeates into a vacuum space defined between the glass sheets of the VIG unit. The edge seals are configured to allow the glass sheets to move laterally relative to one another when the glass sheets experience differential thermal strain and further configured such that viscous shear occurs within at least a portion of the viscous material when there is relative lateral movement between the glass sheets.
