Rocksett is essentially the “gold standard” in the firearms industry for securing muzzle devices (flash hiders, brakes, and suppressors). It’s unique because, unlike standard thread lockers, it thrives in high-heat environments where others fail.
Key Technical Specifications
Rocksett 15017 is an inorganic adhesive that works more like a ceramic cement than a plastic glue.
- Temperature Resistance: Withstands temperatures from -180°C up to 1,100°C.
- Shear Strength: Approximately 450–500 psi at room temperature.
- Cure Time: 24 hours at room temperature (faster if heat-cured).
- Chemical Properties: Resistant to acids, alkalis, oils, and fuels.
Why Use Rocksett Over Red Loctite?
The most common mistake is using Red Loctite (271 or 272) on a muzzle device. Here is why Rocksett is the better choice for this specific application:
| Feature | Rocksett | Red Loctite |
|---|---|---|
| Heat Failure | Remains solid up to 1,100°C. | Liquefies/fails at approx. 230°C–260°C. |
| Removal Method | Boiling Water (it is water-soluble). | High-intensity Torch/Heat. |
| Vibration | Excellent resistance. | Good resistance. |
