Product Description

🏷️ Product Description
Melt Stick-3
🔧 Construction: PP Copolymer-Based Adhesive

The Hot Melt Stick is a heat-sensitive, PP copolymer-based stick used for 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.

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.

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

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.

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 uniform finish.

Frequently Asked Questions
Q What is the PP Hot Melt Stick used for?
The PP Hot Melt Stick is designed to repair small superficial damage, such as scratches, to PP (polypropylene) coatings where the damage does not extend all the way to the bare metal underneath.
Q What tools are needed to apply the PP Hot Melt Stick?
A standard hot air tool (or gas torch), a digital thermometer to verify temperature, a hand grinder for surface preparation, and a scraper or spatula for smoothing are all that is required. No special or expensive equipment is needed.
Q What temperature should the repair area be heated to before application?
The minor repair area should be heated to between 160°C and 180°C (320°F – 356°F). It is recommended to use a digital thermometer to confirm the correct temperature has been reached before applying the material.
Q What are the physical properties of the PP Hot Melt Stick?
The PP Hot Melt Stick has a softening point of 150°C (302°F) per ASTM E-28 testing, and a shear strength of 9 MPa at 23°C (73°F) per ASTM D-1002 testing. Its dimensions are 12.0 in. (305 mm) in length and 1.0 in. (25 mm) in diameter.
Q Is the PP Hot Melt Stick suitable for all types of pipeline coatings?
The PP Hot Melt Stick is specifically formulated for use on PP (polypropylene) coatings and offers excellent adhesion to commercial PE (polyethylene) mill-applied coatings, guaranteeing a high-quality, virtually monolithic coating repair.
Q How does the PP Hot Melt Stick help reduce repair costs?
Its simple stick form eliminates the need for specialized equipment, making the repair process faster, easier, and more convenient. The highly economical formulation and straightforward installation method help keep labor and material costs to a minimum.
