Applications & Uses

Cleaning Information

• Clean tools immediately after use.
• Once cured, the material can only be removed mechanically.

Processing Information

• Suitable Substrates - PUR rigid foam, Various metals, Acrylonitrile butadiene styrene, Polycarbonate, Polyvinyl chloride, Textile, Leather, Wood
• Surface Requirements - Other plastics and metals should be primed, Dry, Clean, Free of grease, Free of dust, Free of oil
• Application Method - Nozzle and Roller
• Lower temperatures than recommended can cause higher viscosity which result in reduced bond strength and reduced wetting.
• Depending on the construction of the equipment, a continuous heating above processing temperature can cause decomposition of the adhesive.
• Tank melters should use protective gases with < 5 ppm humidity, only. Rakoll® 5391 is moisture sensitive, therefore container must be kept closed.
