HexiTherm™ Adhesives for I-joists

I-joist designs are continually being enhanced to work better in a host of applications. Momentive provides a variety of high performance adhesives to improve the strength, versatility and heat resistance of I-joist flange components. With Momentive adhesives, manufacturers are taking designs to a new level.

Third-party, full-scale testing on engineered beams using thermoset-based adhesives has shown that they perform to meet or exceed the highest test criteria.

Whatever your assembly, Momentive provides a broad range of phenolic- and melamine-based adhesives to meet fire rating requirements.
