Loxeal Primer 7 Polyolefin Primer 20ml
Loxeal Primer 7 is a solvent-based surface primer that makes the “unglueable” plastics glueable. Applied before a cyanoacrylate super glue, it raises the surface energy of polyethylene (PE), polypropylene (PP), thermoplastic rubbers, EPDM, PTFE and silicones, transforming bond strength on these notoriously low-energy materials. It dries in seconds, is fluorescent under blue light so coverage can be checked, and is recommended for use with Loxeal Istant 34 and other ethyl cyanoacrylate adhesives. Supplied in a 20ml bottle.
Why choose Loxeal Primer 7?
-
Unlocks polyolefins – makes PP, PE, PTFE, EPDM and silicone bondable with standard super glues
-
Fast and simple – brush on a thin coat, wait a few seconds, then glue as normal
-
Verifiable coverage – fluoresces under a blue lamp for quality control
-
Long working window – primed surfaces stay active for up to one hour
-
Ultra-thin, fluid consistency – roughly 1.5 mPa·s for even wetting of the surface
Typical applications
- Bonding polypropylene and polyethylene parts, containers and housings
- PTFE, silicone rubber and EPDM components that resist ordinary adhesives
- Thermoplastic rubber grips, seals and trims
- Production and repair work on low surface energy plastics
How to use
- Ensure surfaces are clean and dry.
- Brush a thin coat of Primer 7 onto the surfaces to be bonded and let it dry for a few seconds.
- Apply your cyanoacrylate adhesive and press the parts together – handling strength develops within seconds.
- Bond within one hour of priming for best results; reapply primer if more than eight hours pass.
- Reseal the bottle immediately after use.
Usage notes
Primer 7 is intended only for difficult, low surface energy materials – do not use it on substrates that bond readily without priming. Best adhesion is achieved when parts are joined within an hour of application.
