Overview of Permabond POP
Permabond Polyolefin Primer (POP) is an innovative product developed by Permabond to prepare polyolefins and silicones for the application of cyanoacrylate adhesives. Unlike accelerators, Permabond POP does not alter curing rates or affect the pH of acidic surfaces like wood. Its primary function is to enhance adhesion on challenging materials, ensuring precise and uniform results.
Key Benefits of Permabond Polyolefin Primer POP
Polyolefins such as polyethylene (PE) and polypropylene (PP), as well as materials like PTFE and silicones, exhibit low surface energy, making adhesion difficult without pre-treatment. Permabond Polyolefin Primer POP provides an efficient solution:
Improved adhesion
Significantly enhances bond strength on low-energy surfaces.
Efficient alternative
Replaces complex methods like flame or plasma treatment.
UV fluorescence
Ensures application accuracy, as it can be checked under UV light (375 nm).
Note: This product is exclusively designed for polyolefins and silicones bonded with cyanoacrylate adhesives.
Permabond Polyolefin Primer POP Application Instructions
1. Surface preparation
Ensure surfaces are clean, dry, and free of grease before applying the product.
2. Product application
Apply Permabond POP using a clean cloth, brush, dip, or spray method.
3. Drying
Allow it to air-dry at room temperature before bonding.
4. Bonding time
Polyolefins: Bond parts within 2 hours of treatment.
PTFE: Immediate bonding is recommended after treatment.
5. Final curing
Allow the adhesive to cure for 24 hours at 23°C for maximum bond strength.
6. Compatibility testing
Test product compatibility with your specific materials before full-scale use.
Precautions and Storage
Avoid direct mixing: Do not mix Permabond POP with cyanoacrylate adhesives.
Storage conditions: Store between 5 and 25°C.
Industrial hygiene: Follow safe handling practices.
Frequently Asked Questions About Permabond Polyolefin Primer POP
What is Permabond POP’s main function?
It drastically improves cyanoacrylate adhesive bonding on materials such as polyolefins, PTFE, silicones, and some grades of polyester and polyurethane.
Is there a time limit for bonding treated parts?
Yes. Typically, the maximum time for cyanoacrylate adhesive bonding is 2 hours, except for PTFE, which requires immediate bonding after drying.
Which materials do not benefit significantly?
DAP and polyamides: Adhesion strength decreases.
ABS: No noticeable improvement.
Does it work with adhesives other than cyanoacrylate?
No. Permabond POP is exclusively designed for cyanoacrylate adhesives and does not enhance the adhesion of epoxy systems, UV, or acrylic adhesives.
