Cure time is the total time a penetrant is in contact with a component surface.

Explanation:
In penetrant testing, the time the penetrant spends on the surface to seep into defects is called the dwell time (penetration time). Cure time implies hardening or setting of a material, which isn’t how penetrants are handled. After the dwell time, you remove excess penetrant and proceed with development. So calling the total contact time “cure time” is not correct—the correct term is dwell time.
