Applications & Uses

Cleaning Information

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

Preparation Information

Surface Requirements - Other plastics and metals should be primed, Dry, Clean, Free of grease, Free of dust and Free of oil

Processing Information

Lower temperatures than recommended can cause higher viscosity which result in reduced bond strength and reduced wetting. Refer to the technical data table regarding processing parameters. 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® 5258 is moisture sensitive, therefore container must be kept closed.

Suitable Substrates - PUR rigid foam Various metals, Acrylonitrile butadiene styrene (ABS), Polycarbonate (PC), Polyvinyl chloride (PVC) and Textile Leather Wood
