SQ-733002 Dual-Cure Structural/Positioning Adhesive(UV&Thermal)
SQ-733002 is a dual-cure adhesive that combines UV curing with thermal curing. The UV-curable resin relies on photoinitiators to generate free radicals or cations under UV light, initiating crosslinking with advantages of fast curing (seconds) and low energy consumption, but it is less effective on opaque substrates or shaded areas.
The thermal-curable resin is triggered by heat to form a crosslinking reaction, enabling deep curing, but requires longer curing time (from several hours to days). The modified resin introduces dual-curing functional groups (UV-curable double bonds + thermal-curable reactive groups), enabling a synergistic effect of both mechanisms and achieving enhanced overall performance.
