Product Description
Bostik Born2Bond™ HHD 5539BK is a one-component, solvent-free, moisture-curing polyurethane adhesive. Once dispensed, this adhesive reacts with ambient moisture or the water content of substrates to form a cross-linked thermoset structure. HHD 5539BK also contains a fluorescent agent, enabling UV inspection for easy quality control. This high-performance adhesive is specifically designed for touch panel bonding, providing superior adhesion and durability for a wide range of applications.
