In a low-temperature environment, what changes occur in the photoinitiators within UV adhesive?
News 2025-12-30
Low temperatures can significantly reduce the decomposition efficiency of traditional photoinitiators, causing the curing speed of UV adhesive to slow down at 5°C.
The solution is to use excited-state energy transfer to increase the initiation efficiency at -10°C to 80% of that at room temperature.
UV adhesives on the market generate high temperatures instantly upon exposure to ultraviolet light due to the curing reaction.
