Edgetherm® 3500 Single-Part Butyl Sealant

Quanex’s Edgetherm® 3500 is a single-part butyl 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, helping you build greater efficiency into your fabrication process.

A combination of high output and fast heat-loss properties reduces the risk of corner defects for a complete seal around the unit. If you’re looking to improve efficiency and consistency in your insulating glass manufacturing process, this is the right sealant for you.
