Application and Clean-up

Coating surface area should be clean and free of any oils, residues, dust or any other contaminants.

Typical equipment: A hot melt application equipment capable of maintaining the suggested adhesive temperature noted above and appropriate for the application. An inert nitrogen blanket is suggested (not required).

General application:
(1) Purge the previous hot melt adhesive from the equipment.
(2) Set the equipment temperature to the suggested settings above.
(3) Adjust the pump pressure for the desired adhesive amount.
(4) The open and set time characteristics may be modified with small adjustments to the amount of the applied adhesive and equipment temperature settings. Cleaning: Consult the equipment manufacturer for cleanup procedures.

Safety & Health

Safety and Disposal

To minimize the risk of burns, we recommend the use of eye protection and protective clothing when working near a hot melt applicator. To minimize the risk of flammable vapors, do not exceed a melt temperature above 400 °F. Prevent the build-up of vapors. Extinguish all sources of ignition during hot melt use. Please refer to the SDS for additional safety advice.
