(1) Solvent-free, one-component type. Unlike solvent-based adhesives, which requires a drying process, there is no problem of environmental pollution and poisoning due to the existence of solvents. The bonding process is simple and can be applied by roller coating or spraying, and is suitable for various automated assembly lines.
(2) It can be glued at low temperature. The melting temperature of the polyurethane reactive hot-melt adhesive is lower than the service temperature of the general hot-melt adhesive (170-200 ℃), and it can be glued at low temperature and can be used at 120-150 ℃. Save energy and reduce the corrosiveness of the glue applicator, especially suitable for bonding heat-sensitive materials (such as plastics, etc.).
(3) Good operability. The two adherends can be fixed in a short period of time, so the assembly can be quickly transferred to the next processing process to improve work efficiency.
(4) Long pot life: 16h for 150°C, 3 days for 90°C.
(5) Excellent heat resistance, cold resistance, water vapor resistance, chemical resistance and solvent resistance. Compared with the original hot-melt adhesive, the listed properties are greatly improved due to the cross-linked structure of the reactive hot-melt adhesive.
