← ScienceWhich consequence results when epoxy resin hardening fails?
A)Substrate corrosion at bonded interface✓
B)Increased tensile shear bond strength
C)Reduced susceptibility to thermal creep
D)Enhanced UV resistance of adhesive
💡 Explanation
Incomplete curing leaves unreacted monomers, weakening the polymer matrix. Because the polymer network does not fully form via crosslinking, water permeates the epoxy interface due to weak van der Waals forces, therefore corrosion risk increases rather than material being fully functional.
