Applicable Base Polymer Properties
Because of their thermosetting molecular structure, epoxy adhesives exhibit excellent tensile-shear strength but poor peel strength unless modified with a more resilient polymer.
Characteristics of many high-quality epoxy adhesives include:
- Excellent resistance to oil, moisture, and many solvents
- Low shrinkage on curing
- high resistance to creep under prolonged stress
Epoxy resins have no evolution of volatiles during cure and are useful in gap-filling applications.
