Plastic Bonding Adhesives
How to choose the best adhesive for bonding plastics — including difficult low-energy substrates.
The best adhesive for plastic depends on the plastic type: cyanoacrylate for fast bonds on many rigid plastics, epoxy for structural strength, and UV adhesives for clear plastics. Low-energy plastics like PP and PE need surface treatment.
Plastics vary widely in bondability. Rigid plastics bond well with epoxy or cyanoacrylate, while low-surface-energy plastics like PP and PE need surface treatment or specialised adhesives.
JOME supplies epoxy, cyanoacrylate and UV adhesives for plastic bonding, with guidance on the right grade and surface preparation for your material.
- Identify the plastic type first
- Clean and degrease surfaces
- Treat low-energy plastics (PP, PE)
- Use cyanoacrylate for fast fixturing
- Use epoxy for structural strength
- Use UV adhesives for clear plastics
- Test adhesion before production
- Control gap and bond-line
Cyanoacrylate suits fast bonding of many rigid plastics, epoxy gives structural strength, and UV adhesives bond clear plastics cleanly. The best choice depends on the plastic type.
PP and PE are low-energy plastics that resist bonding. Use surface treatment (flame, plasma or primer) with a suitable cyanoacrylate or specialised adhesive.
Yes. Epoxy adhesives bond most plastics to metal; flexible polyurethane is useful where the joint must absorb movement.
