Description
Permabond POP Primer is a surface treatment designed to improve adhesion when bonding difficult plastics with cyanoacrylate adhesives. Supplied in a 50ml bottle, this primer is used before applying Permabond cyanoacrylate adhesives to increase bond strength on low surface energy materials such as polypropylene (PP), polyethylene (PE), PTFE, and silicone.
Plastics such as polyolefins and fluoropolymers are naturally difficult to bond due to their low surface energy. By applying Permabond POP primer before bonding, strong and durable bonds can be achieved, often exceeding the strength of the substrate itself.
The primer is easy to apply by wiping, brushing, dipping, or spraying onto the surface. Once dry, cyanoacrylate adhesive can be applied to create a fast curing, high strength bond. Permabond POP is commonly used in engineering, automotive, plastics fabrication, maintenance, and production environments where reliable bonding of difficult materials is required.

FAQ – Permabond POP Polyolefin Primer
What is Permabond POP primer used for?
Permabond POP is a polyolefin primer designed for surface treatment of low surface energy plastics before bonding with cyanoacrylate adhesives. It is commonly used when bonding polypropylene, polyethylene, PTFE and silicone, which are normally difficult to bond without special surface preparation.
Why is primer needed for polypropylene and polyethylene?
Polypropylene (PP), polyethylene (PE) and similar plastics have very low surface energy, which makes it difficult for most adhesives to form a strong bond.
Applying Permabond POP primer helps prepare the surface so cyanoacrylate adhesive can achieve significantly improved bond strength.
Can Permabond POP increase bond strength?
Yes, when used correctly, Permabond POP can greatly improve adhesion to difficult plastics. In many cases, bonds made with primer and cyanoacrylate adhesive may exceed the strength of the plastic itself, depending on the materials and conditions used.
Users should always test the product under their own conditions before full production use.
What materials is Permabond POP suitable for?
Permabond POP is typically used when bonding:
- Polypropylene (PP)
- Polyethylene (PE / HDPE / LDPE)
- PTFE and fluoropolymers
- Silicone rubber
- Some engineering plastics
It may also improve adhesion on certain other low surface energy materials. Results may vary depending on the exact grade of plastic.
Does Permabond POP work with all plastics?
No. Permabond POP is designed mainly for low surface energy plastics.
It may not improve bonding on materials such as ABS, and in some cases may reduce strength on certain plastics. Testing is recommended before use.
How is Permabond POP applied?
The primer can be applied by wiping, brushing, dipping or spraying onto the surface.
Surfaces should be clean, dry and free from grease before application.
After applying the primer, allow it to dry fully before applying the cyanoacrylate adhesive.
How long after priming can parts be bonded?
For most polyolefin plastics, bonding with cyanoacrylate adhesive can usually be carried out within approximately two hours after primer application.
For PTFE and similar materials, bonding should normally be carried out as soon as possible after the primer has dried.
Does Permabond POP need to be mixed with the adhesive?
No. Permabond POP must not be mixed directly with cyanoacrylate adhesive.
The primer is applied to the surface first, allowed to dry, and the adhesive is then applied separately.
Can Permabond POP be used in production environments?
Yes, Permabond POP is commonly used in engineering, plastics fabrication, automotive and industrial assembly where reliable bonding of low surface energy materials is required.
As with all adhesives, suitability should be confirmed by testing under actual operating conditions.
How long does Permabond POP take to dry?
At normal room temperature, Permabond POP typically dries in around 30 seconds.
Drying time may vary depending on temperature, ventilation and application method.
