Motorex High-Temp Copper Anti-Seize Lubricant Paste

Motorex Copper Anti-Seize Paste is engineered for industrial-grade performance in environments where standard lubricants fail. Whether you’re working on scorching hot exhaust systems or freezing outdoor machinery, this copper-based compound delivers unmatched protection against corrosion and seizing across an extraordinary temperature spectrum—from -40°C up to 900°C, with brief tolerance even beyond 1200°C. Its unique formula combines paraffinic base oil for reliable lubrication at moderate temperatures (up to 280°C) with copper particles that activate under extreme heat, ensuring seamless operation in high-stress scenarios like turbocharger installations or steam valve fittings.

Designed for precision assembly tasks, this paste excels at preventing metal-to-metal friction corrosion and jamming in threaded connections and press fits. Unlike competitors that rely on graphite or molybdenum disulphide, Motorex’s copper-rich composition offers superior thermal stability and no toxic lead additives, making it ideal for applications requiring long-term durability without compromising safety. Users in automotive repair shops, industrial plants, and heavy equipment maintenance report effortless bolt removal after years of exposure to steam, chemicals, or thermal cycling—a testament to its robust corrosion barrier properties under pressure.

Key Advantages vs Competitors
| Feature | Motorex Copper Paste | Graphite/MoS₂-Based Pastes |
|————————–|—————————-|———————————-|
| Temperature Range | -40°C to 1200°C (short term)| Limited above 400°C |
| Corrosion Resistance | Copper provides permanent barrier | Temporary protection |
| High-Pressure Use | Optimized for press fits | Not recommended for heavy loads |
| Toxic Materials | Lead-free | May contain harmful additives |

Ideal for exhaust components (e.g., headers), boiler fittings, and machinery exposed to aggressive conditions like saltwater or high-pressure steam. A dab applied with a brush ensures tight seals without leaving residue or causing electrical interference—a critical benefit for automotive turbo systems or electrical connectors prone to oxidation. Avoid using on roller bearings or fast-spinning slide bearings where rotational speeds exceed its design limits.

For mechanics facing stubborn bolts or engineers needing reliable lubrication in extreme thermal environments, Motorex Copper Anti-Seize Paste is your go-to solution when standard products fall short.
