Arexons System AN251: The Ultimate Barrier Against Heat and Corrosion
Anyone who works on engines or industrial systems knows the problem of bolts "welded" by heat and rust. Arexons System AN251 Anti-Seize Copper Sealant (code 4251) is the professional solution based on flake copper and oxidation inhibitors. This high-tech paste is more than just a grease: it's a protective film that prevents metal-to-metal contact under extreme pressure, ensuring easy disassembly even after years of operation in critical conditions.
Why is AN251 Copper Paste essential for your workshop?
The use of AN251 anti-seize prevents structural damage and drastically reduces maintenance times, offering unique technical advantages:
- High Temperature Shield: While traditional greases carbonize, the copper contained in AN251 remains active up to 1100°C, lubricating the threads and preventing accidental breakage during unscrewing.
- Mechanical Compatibility: Excellent for the lubrication of threaded fittings, boiler flanges, heat exchangers and turbine bolts.
- Automotive Application: Essential in the assembly of spark plugs, injectors, exhaust joints and moving parts of the braking system subject to high heat.
- Chemical Stability: Resists washing with water and is not altered by acids or saline solutions.
Technical Specifications
A product calibrated for the most demanding workloads in heavy industry:
- Format: 500g jar.
- Color: Copper.
- Dropping point: None (does not drip).
- Thermal Resistance: Up to +1100°C.
- Composition: Synthetic oil, inorganic thickener and pure copper.
Instructions for optimal application
- Cleaning: Clean and degrease the metal parts to be treated with a specific detergent to remove residues of old lubricants.
- Application: Apply an even amount of copper paste to the contact surfaces (threads, flanges, etc.) using a brush or spatula.
- Assembly: Proceed to tighten the components. The paste will spread, filling every microporosity in the metal.
- Excess Removal: Remove any external excess, although the product will not damage surrounding surfaces.
Frequently Asked Questions
Can I use it on disc brake pads?
Yes, but only on the metal back and the caliper guides. It must absolutely not come into contact with the pad friction material or the disc surface.
Is it conductive? Is it suitable for battery terminals?
Copper is conductive, but Arexons AN251 is primarily formulated as an anti-seize lubricant. For battery terminals, it's best to use specific products such as Vaseline grease or dedicated protectors.
What is the difference between copper grease and lithium grease?
Lithium grease is a general purpose lubricant for bearings and fast movements at medium temperatures. Copper anti-seize (AN251) is specifically designed to protect static or loose fasteners subjected to extreme heat where lithium would burn.
Does this product dry out over time?
Arexons AN251 is designed to resist drying and hardening. The synthetic base and copper flakes maintain their protective effectiveness for years, making future disassembly easier.
