Some materials, such as nylon, rubber, fibreglass and metal are difficult to bond, especially if they have a smooth surface and need to be adhered to another material that does not bond well. To do the job, you need a specially formulated Polypropylene/polythene adhesive specifically designed to work with hard-to-bond materials. With a proper prep job, even application and a long enough curing time, these adhesives have the special ability to unite even the most difficult materials to bond.

Moderately Easy

Things you need

  • Specially formulated Polypropylene/polythene adhesive

  1. 1

    Sandpaper the surface with a 120-grit sheet of sandpaper if the surface is smooth. If not, proceed to Step 2. Clean dirt, sanding particles and debris from the surface.

  2. 2

    Load the adhesive cartridge into the dispensing gun and remove the cap.

  3. 3

    Dispense adhesive by applying equal pressure until a uniform colour and consistency is achieved.

  4. 4

    Attach materials within three minutes.

  5. 5

    Allow at least 48 hours to cure. Curing time decreases with increased ambient temperature.

Tips and warnings

  • Avoid skin contact because the adhesive can cause irritation or rash.
  • Wear protective equipment -- safety glasses and gloves -- when applying adhesive.
  • Perform the bonding procedure in a well ventilated area.
  • Do not apply adhesive in temperatures below 4.44 degrees Celsius as the adhesive will not bond properly.
