Product Name
Permabond Cyanoacrylate 799 Instant Adhesive-for Difficult Plastics & Rubbers
Brief Description
Permabond 799 is a high-viscosity, surface-insensitive cyanoacrylate adhesive engineered for rapid bonding of difficult plastics and rubbers, as well as porous materials. It is also highly effective for filling large gaps, minimizing wicking into porous surfaces, and providing exceptional strength on a wide range of substrates. This single-component adhesive cures quickly at room temperature upon contact with surface moisture.
Popular Applications & Uses
- Bonding porous substrates such as wood, foam, fabric, and rubber- Large gap-filling applications in industrial bonding- High-speed production line assembly- Model assembly- Jewelry assembly- Ceramics bonding- Speaker bonding- Fabric and leather bonding- Medical device assembly- Automotive applications, including bonding composites, plastics, and leather
Industries that Commonly Use It
- Aerospace/Defense- Artist, Artisan- Automotive Service/Repair- Chemical Industry- Cladding- Construction/ Building Services- Distributers & Resellers- General Manufacturing- Government & Military- Industrial Supply- LED/Electronics- Marine- Medical Device/ Prosthetics- Metal Fabrication- Military- Plastic Fabrication- Prosumer- Sign & Display- Special Effects/ Scenic Design- Tarp, Fabric, Awning Manufacturing- Transportation/ Specialty Vehicle
Special and Unique Features
- High-viscosity for large gaps, up to 0.5 mm (0.02 in)- MIL-SPEC Compliant: Meets MIL-A-46050C Type II, Class 3, suitable for military, aerospace, and industrial applications- Fast-setting formula, achieving handling strength in approximately 8 seconds- Surface-insensitive, curing rapidly on most surfaces and minimizing frosting and fogging- Minimizes wicking into porous surfaces, making it ideal for wood, fabric, foam, and rubber- 100% solids, solvent-free formulation- Single-part, no mixing or heat cure required- Provides high strength and impact resistance

Known backups / known substitutes
- Loctite® 380- 3M™ Scotch-Weld™ CA100- Permatex® Black Super Glue- Other Permabond cyanoacrylates such as Permabond 731, 735, 737 (toughened grades for improved impact and peel resistance)- Permabond 795 (for acidic surfaces)- Procure branded cyanoacrylates (as alternatives)
Comparison Note
Permabond 799 stands out as a premium, high-strength cyanoacrylate adhesive, particularly noted for its high viscosity and ability to cure effectively through larger gaps and on porous or difficult-to-bond surfaces where standard instant adhesives might wick away or struggle. Its surface-insensitive nature and MIL-SPEC compliance make it a robust choice for demanding industrial, aerospace, and military applications, offering a reliable alternative to comparable products from other leading brands.
