How are tackifiers activated?

By heat

By moisture

By ultraviolet light

Pressure dependent—30 seconds or longer

Tackiness in these adhesives is activated by contact pressure over a short period. When you press firmly and hold, the adhesive wets the skin or barrier surface, the polymer chains rearrange, and intimate contact is achieved. This time allows the tack to develop fully, giving a reliable seal—about 30 seconds in typical use.

Heat or moisture can influence how the adhesive behaves, but the essential activation mechanism is sustained pressure with a brief hold. UV light isn’t involved in activating tack.
