Permabond 790 Instant Adhesive

Description

Permabond® 790 is an ultra-fast setting, low-viscosity cyanoacrylate adhesive designed for surface-insensitive bonding, including acidic materials like wood, plated surfaces, and difficult-to-bond plastics, metals, ceramics, and elastomers. Its wicking formula makes it ideal for post-assembly applications, micro-crack sealing, and precision bonding.

This single-component adhesive cures rapidly at room temperature upon contact with surface moisture. It meets MIL-SPEC MIL-A-46050C Type II, Class 1, ensuring compliance for military, aerospace, and industrial applications.

For customers seeking alternatives to Loctite® 420, 3M™ Scotch-Weld™ CA40H, or Permatex® Surface-Insensitive Super Glue, Permabond 790 provides an ultra-fast, high-performance solution.

Directions for Use

1. Ensure surfaces are clean, dry, and grease-free. Use acetone or isopropanol for best results.
2. Apply Permabond 790 sparingly to one surface only.
3. For wicking applications, allow the adhesive to seep naturally into joints or cracks.
4. Quickly align and press components together. Apply even pressure to ensure a thin, even adhesive film.
5. Hold in place for 2-3 seconds until initial bond forms.
6. Allow 24 hours for full strength development.
7. For difficult or porous surfaces, use Permabond CSA or QFS 16 Activator.

🔹 Note: For bonding polypropylene, polyethylene, PTFE, or silicone, use Permabond Polyolefin Primer (POP) before applying adhesive.
