← ScienceWhich risk increases when epoxy adhesives experience electron beam radiation?
A)Reduced adhesive bond strength✓
B)Increased thermal conductivity
C)Greater resistance to solvents
D)Enhanced electrical insulation
💡 Explanation
Reduced adhesive bond strength occurs because radiation-induced scission disrupts covalent crosslinking. Chain scission weakens intermolecular forces; therefore, the adhesive fails at lower stress, rather than gaining other characteristics under radiation.
