The principle of using PUR hot melt adhesive: try to use it up within 24 hours after dismantling it, do not heat it continuously for more than 6 hours, and do not heat the same glue three times.
If the morning is not used up, and I have to rest at noon, how can I continue to use it in the afternoon?

1. When the PUR hot-melt adhesive is not finished in the morning, do not turn off the dispenser, keep the dispenser in the preheating state, and keep the PUR hot-melt adhesive at 80°C to ensure that the PUR hot-melt adhesive does not cool down. You can continue to use it in the afternoon.
2. It can be turned off and used again after changing the needle in the afternoon. Before using it, let it dispense a little glue to ensure normal use.
3. If the time is long enough, try to block the outlet with something to prevent the air from curing the glue at the outlet, and let the unsealed glue be used up within 24 hours.

Pay attention to the storage method of hot melt adhesive:
PUR hot melt adhesive should be stored in a dry, cool place, avoid sunlight exposure, and prohibit contact with steam, water and alcohol solvents. The shelf life is generally 12 months.
