PUR polyurethane hot melt adhesive

   Application areas    9330 is a moisture curing reaction type hot melt adhesive suitable for automatic edge sealing machine, which can be used for various edge sealing materials; Such asHPL/CPL/poly/PVC/ABS/ PP/PMMA/ 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     At 140 ℃, opening time (s): about 8 ± 2     (Cross-linking) reaction time (d): about 4-7     Use temperature: 130-140℃     Bush viscosity (on the day of production) RVDV2T 8#:  75,000 cps (140℃)     Heat resistance (°C) …
