Reactive polyurethane hot-melt adhesive 8131
Luxbond 8131 is a one-component moisture-cured reactive hot-melt polyurethane adhesive designed for bonding various substrates. This solvent-free, 100% solids product offers fast setting, short clamping time, and high strength; it is solid at room temperature and requires heating for use; when heated and applied, 8131 reacts with moisture in the air to cure into a durable, flexible polyurethane bond that meets the bonding and sealing requirements of electronic products, suitable for bonding and sealing most plastics and metals. This product has excellent moisture resistance.
