Understanding Low Outgassing Adhesives

Engineers often want to know whether an adhesive is low outgassing or generic. And while there are cases when nothing but a low outgassing product will do, the truth is that many so-called generic adhesives inherently have low outgassing levels. What's more, most bonding, potting, encapsulation and sealing...
