Activator, Explained
Quick definition
The liquid catalyst that hardens dip powder without any UV lamp.
Dip systems stack resin + powder + activator: the activator triggers instant polymerization, turning layered powder rock-hard in seconds.
It's the reason dips need no lamp — and why thin, even layers matter; thick activator pools create heat spikes and uneven hardness.
