Product Description
Permabond® 799 Cyanoacrylate is a high-viscosity, surface-insensitive adhesive that combines extremely fast curing with the ability to fill large gaps up to 0.5 mm. This 100% reactive, solvent-free formula minimizes frosting and fogging during cure and is particularly well-suited for porous substrates, as it fixtures before wicking into surface pores. It delivers rapid, high-strength bonds on a variety of materials, including plastics, metals, ceramics, and elastomers.
Key features
- Extremely fast setting: Polymerizes rapidly to achieve handling strength in just 8 seconds on steel, rubber, and phenolic surfaces.
- High viscosity: Specifically formulated with a 5000 cP viscosity to cure through large gaps and excel on porous substrates without premature wicking.
- Industry approved: Approved to stringent military specifications, including MIL-A-46050C Type II Class 3 for existing designs.
Applications / Suitable for
- Bonding plastics, metals, ceramics, and elastomers
- Large gap filling applications up to 0.5 mm
- Porous substrates where adhesive wicking must be prevented
