Does epoxy break down?

Epoxy is very resistant to wear, cracking, peeling, corrosion and damage from chemical and environmental degradation. Once cured, epoxy is moisture resistant.

How long does it take for epoxy to decompose?

The decomposition rate of resin increases rapidly at the reaction temperature, and reaction time is increased. Some sources claim it takes between 5 to 7 days for compostable resins to decompose.

Does epoxy degrade over time?

Epoxies are particularly susceptible to prolonged UV exposure. For this reason when used in boat-building they are more often employed for the inner structure rather than the outer surface. Sunlight doesn’t just discolour epoxy, it degrades it.

Why is epoxy so expensive?
