KRYLEX® KH409
- Chemical Family
- Polyurethanes (PU)
KRYLEX® KH409 is a one component reactive polyurethane hot melt. It is solid at room temperature. This is a low viscosity and temperature adhesive. After being applied warm the product will cool to allow immediate handling. Upon further exposure to ambient humidity KRYLEX® KH409 will achieve high strength bonds and excellent environmental resistance.

- Parameter Setting
The following data is the best data obtained from repeated adjustments according to the production requirements. Different users, due to different production equipment, may need to reset some data. The following data is for reference only.
- Use Instructions
For best results, ensure parts are clean, dry and free from oil and grease, although good bonds can still be achieved on 'as received' or slightly oily parts. The temperature of substrate should not be lower than 20℃. Low temperature will shorten the open time and cause the bonding failure. If needed, pre-heating of the substrate is recommended. Dispense bead of product onto substrate. Mate opposite substrate within recommended open time. Allow for handling strength to be achieved.
