Product Description

PP Hot Melt Stick

Construction: PP Copolymer-Based Adhesive

The Hot MELT STICK is a heat-sensitive, PP copolymer-based stick used for repairing small superficial damage (scratches) to PP-coatings where the damage does not extend to the bare metal. Installation is done with a standard gas torch or hot air tool.

  • 1

    Using a hand grinder, chamfer the edges of the polypropylene coating surrounding the damaged area until a smoothly contoured surface is obtained in the repair area.

  • 2

    Using the hot air tool, heat the minor repair area to 160 - 180℃. Using the digital thermometer, ensure the correct temperature has been reached.

  • 3

    While holding the cut-to-length PP Melt Stick/Strip, use the hot air tool to heat the end of the material until it becomes soft and flexible.

  • 4

    Fill the affected area with the heated PP Melt Stick/Strip. Use the hot air tool to heat the PP Melt Stick/Strip until it is soft and pliable. Force the activated material into the repair area or depression with a scraper / spatula, heating and smoothing to achieve a seamless finish.
