PUR barrel hot melt adhesive

Application areas:      9300 is a wet curing reaction type PUR hot melt adhesive suitable for automatic edge sealing machine, aluminum honeycomb special type hot melt adhesive, can be used for a variety of edge sealing materials;Such as HPL / CPL / Poly / PVC / ABS / PP / PMMA / SPC / Aluminum honeycomb solid wood or wood veneer.      Features and usage methods：      Quick curing, high initial bonding strength; The glue layer has good elasticity at low temperature and does not become brittle. Good resistance to solvents. The humidity of the surrounding environment and the moisture content of the material determine the length of the cross-linking reaction, which generally takes a few days. After curing, it is an irreversible thermosetting adhesive film. After complete curing, it can be soaked in water.     Basic properties：     Base material: polyurethane & isocyanate ester     At 140 ℃, opening time (s): about 8 ± 2    (Cross-linking) reaction time (d): about 3-8     Use temperat…
