← ScienceWhich consequence results when epoxy adhesive's covalent network degrades?
A)Reduced structural shear strength✓
B)Increased thermal conductivity
C)Greater electrical breakdown resistance
D)Enhanced optical transparency
💡 Explanation
Bond degradation in an epoxy weakens the adhesive because chain scission reduces crosslinking density. Therefore, shear strength decreases, rather than alternatives like increased conductivity or optical changes because cohesive forces are directly correlated to the molecular bonding.
