- Up to 8-Hour On-Part Life
Product Description
LOCTITE SF 7951 is a very-low-viscosity cyanoacrylate surface primer for polyolefin and other low-energy substrates. It is applied by spray, brush or dip and allowed to dry before cyanoacrylate adhesive application. The primer is recommended for difficult-to-bond polyethylene, polypropylene, PTFE and thermoplastic rubber. Typical drying time is 20 to 40 seconds at 25 deg C, and the treated surface has an on-part life of up to 8 hours. The product is not recommended for assemblies where high peel strength is required.
Key features
- Low-energy surface priming: Prepares difficult-to-bond polyolefin and related low-energy substrates for cyanoacrylate bonding.
- Fast ambient drying: Typical drying time is 20 to 40 seconds at 25 deg C.
- Extended on-part life: The primed surface remains active for up to 8 hours.
Applications
Priming low-surface-energy materials such as PE, PP, PTFE and TPE before cyanoacrylate bonding.
