Edgetherm® 3100


Quanex’s Edgetherm® 3100 is a single-part, butyl rubber-based sealant that sets quickly from its molten state, allowing units to be moved from their assembly locations between two and five minutes after application and glazed the same day. A combination of high output and fast heat loss properties reduce the risk of corner defects for a complete seal around the unit.

  • Available in black
  • Can be used as a secondary seal in conjunction with a PIB primary sealant
  • Convenient pack size for easy storage
  • Quick setting from molten state
