LOCTITE® HHD 3624WH is a one-component polyurethane hot-melt adhesive with 100% solids content. It cures through moisture and solidification, providing low modulus, high aspect ratio, and good reworkability. The white adhesive is suitable for automatic or manual assembly processes and is ideal for sealing, hole-filling, and electronic device assembly. It exhibits slight odor and achieves high handling strength immediately after application.
