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.
- Skill level:
- Moderately Easy
Things you need
- Specially formulated Polypropylene/polythene adhesive
- Glue dispensing gun
- 120-grit sandpaper
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.
Load the adhesive cartridge into the dispensing gun and remove the cap.
Dispense adhesive by applying equal pressure until a uniform colour and consistency is achieved.
Attach materials within three minutes.
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.
