Loctite SF 7701 Primer 473ml Bottle

Loctite SF 7701 is a colourless, solvent-based primer for surface preparation. It is used to improve the bonding properties of cyanoacrylate adhesives on polyolefins and other low energy surfaces. Loctite SF 7701 is effective on difficult-to-bond substrates such as polyethylene, polypropylene, polytetrafluoroethylene (PTFE) and thermoplastic rubber materials. Use of this product is not recommended in assemblies where high peel strength is a requirement.

Loctite SF 7701 is an aliphatic amine-based product. It also works as an activator, accelerating the cure speed of instant adhesives. Fixturing time on most substrates primed with Loctite SF 7701 is less than 5 seconds at room temperature. This product has been tested to the protocols based on ISO 10993, making it suitable for use in the assembly of disposable medical devices.

• Improves adhesive properties of instant adhesives
• Only use on polyolefins and other difficult-to-bond materials
• Fluorescent under UV light
• ISO 10993 biocompatibility standards approved

How to use Loctite SF 7701:

1. Apply Loctite SF 7701 by spraying, brushing or dipping. Use product at room temperature.
2. Avoid applying excess primer. Presence of primer can be detected by means of a UV inspection lamp (365 nm).
3. If working with polyolefin and easier to bond materials, apply the primer to the polyolefin only.
4. Assemble parts immediately.
5. Secure the assembly and await fixturing before any further handling.

Storage

Store Loctite SF 7701 in the unopened container in a dry location. Optimal Storage: 8° C to 21° C. Storage below 8° C or greater than 28° C can adversely affect product properties.
