C-4438

Brief Introduction:

C-4438 is a photo-curable resin developed for bonding U-shaped iron inside speakers to speaker adhesive bases. It hardens rapidly under UV light and provides strong bonding properties. After curing, the resin’s adhesion strength is so high that it will damage the substrate rather than debond. It is resistant to drop, impact, high temperature (+85°C), high humidity (95%), and thermal shock.
