About MOLYKOTE® CU-7439 Plus Paste V1

OVERVIEW:

MOLYKOTE® CU-7439 Plus Paste V1 is a high-performance copper-based assembly and anti-seize paste formulated for metal/metal combinations operating under extreme loads and very high temperatures. It provides reliable protection against seizure, galling, fretting, and corrosion, even after long-term service in harsh environments. CU-7439 Plus Paste is ideal for threaded fasteners, press fits, and components exposed to heat, moisture, and corrosive atmospheres.

KEY FEATURES:

High Temperature Resistance
Performs effectively from approximately -30°C to +1100°C, making it suitable for high-temperature applications.

Excellent Load-Carrying Capacity
Provides reliable wear protection and extreme-pressure (EP) performance under high static and dynamic loads.

Prevents Seizure and Galling
Forms a durable lubricating film that prevents metal-to-metal welding, stick-slip, and seizure, facilitating easy disassembly.

Corrosion Protection
Offers excellent protection against corrosion, even in humid, salty, or chemically aggressive environments.

Facilitates Assembly and Disassembly
Enables easy and damage-free disassembly of fasteners and components after long-term service at high temperatures.

APPLICATIONS:

• Threaded Fasteners – Lubrication of bolts, screws, studs, and flanges exposed to high temperatures or corrosive environments.

• Press Fits and Interference Fits – Prevents fretting and galling during assembly and operation of press-fit components.

• Sliding Guides and Tracks – Suitable for guide rails, cams, and other sliding surfaces subjected to high thermal and mechanical loads.

• Brake System Components – Used in brake assembly applications to prevent seizure and ensure reliable operation.

• Industrial Equipment Maintenance – Ideal for anti-seize and protective lubrication in turbines, heat exchangers, chemical processing equipment, and exhaust systems.

PACKAGING:

MOLYKOTE® CU-7439 Plus Paste V1 is typically supplied in various packaging formats such as 100g tubes, 500g cans, and larger containers depending on regional availability and application needs.

INSTRUCTIONS FOR USE:

• Surface Preparation: Clean and dry all surfaces to remove dust, oxides, oils, old lubricants, and contaminants to ensure optimal adhesion and performance.

• Application: Apply a thin, uniform layer of paste to the target surfaces using a brush, cloth, or suitable applicator. A thin film is sufficient for effective anti-seize protection.

• Maintenance: Reapply as needed based on wear, operating conditions, and maintenance intervals.

SAFETY AND HANDLING:

MOLYKOTE® CU-7439 Plus Paste V1 contains copper and should be used in well-ventilated areas. Avoid contact with eyes and skin. Use appropriate personal protective equipment such as gloves and goggles. Keep away from open flames and sources of ignition. Refer to the product’s Safety Data Sheet (SDS) for complete safety, handling, and disposal information.
