These terms refer to the waiting period required between the time you mix and the time you can start applying a two-part product, such as an epoxy. This allows the necessary chemical reactions between the two parts to begin so the coating will cure and perform properly.
Also, What happens if you don’t paint your sweat?
Insufficient induction times in coatings or paints cause coating failures. For example, many epoxy coatings require a fixed time interval in order to make the epoxy resin and hardener fully compatible. When this pre-reaction time is not met, it will produce poor a film appearance and poor coating performance.

Conclusion. The effects of mixing a two-component material at a ratio that is different from the ratio specified by the manufacturer can cause a wide range of defects, and some of these defects can lead to coating failure.
What does gel time mean?
Gel time is the time it takes for a mixed resin system to gel or become so highly viscous that it can no longer be considered workable or able to be handled.

This interval corresponds to the period during which any remaining com- ponent causes in the etiologic sequence contribute to the causal process.
