About Structural Adhesives

Slow-Set Epoxy Structural Adhesives
To allow time to adjust and position parts, these epoxies remain workable for at least 90 minutes. The strongest and most weather- and chemical-resistant structural adhesives, epoxies work especially well on metals.
These have two parts that must be mixed. The size listed is the combined total of the two parts. Adhesives that meet ASTM E595, a standard used by NASA, produce almost no volatile emissions that could damage sensitive electronics and optics, even in a vacuum.
