MOLYKOTE P-37 Paste – 1 Kg Pack

Product Overview

MOLYKOTE P-37 Anti-Seize Paste is a specialized solid-lubricant paste developed for bolted joints and threaded connections exposed to extremely high temperatures. Manufactured under the MOLYKOTE brand by DuPont, it is designed to help prevent seizure and support easier disassembly of compatible fasteners after prolonged exposure to severe operating conditions.

The formulation uses mineral oil and special solid lubricants, including graphite and zirconium dioxide. The product is designed for applications where purity and controlled lubricant composition are important, particularly when conventional anti-seize products containing certain metallic contaminants are unsuitable.

MOLYKOTE P-37 is intended for screws, nuts and bolts made from heat-resistant or extremely heat-resistant steels, including selected nickel-based alloys. It has been used for bolted connections in gas and steam turbines in power stations.

Key Features and Benefits

High-Temperature Performance

MOLYKOTE P-37 is designed for high-temperature threaded connections. The manufacturer lists a temperature capability of up to 1,400°C for the solid-lubricant system. This figure relates to the solid lubricants’ temperature resistance and should not be interpreted as the continuous operating limit of the complete paste under every condition.

Anti-Seize Protection

The paste helps reduce the risk of fasteners seizing during service. This is especially useful for specified bolted joints that must be dismantled for inspection, maintenance or component replacement after exposure to high temperatures.

Easier Disassembly

MOLYKOTE P-37 is formulated to help screws and bolts remain removable even after extended periods of use at elevated temperatures. Actual results depend on the fastener material, surface condition, temperature history, tightening procedure and operating environment.

High Load-Carrying Capacity

The product offers high load-carrying capacity for appropriate threaded connections. Its solid-lubricant formulation helps support lubrication where conventional oils and greases may not provide the required anti-seize performance.

High-Purity Formulation

The manufacturer describes MOLYKOTE P-37 as an extremely pure solid-lubricant paste. It is formulated without intentional lead, nickel, sulfur, chlorine or fluorine. Published specifications also place limits on sulfur and total halogen impurities.

These characteristics make the product relevant to applications where lubricant purity is an important selection criterion. Always check the current technical documentation against the specific equipment or industry requirements.

Low Seepage

The manufacturer identifies low seepage as a benefit, which can be useful in applications where cleanliness around the connection is important.

Applications of MOLYKOTE P-37 Paste

MOLYKOTE P-37 is intended for selected threaded connections and fasteners operating under severe conditions, including:

• Gas turbines: Specified bolted joints in power-generation equipment.
• Steam turbines: Fasteners exposed to demanding thermal conditions.
• Power stations: Compatible bolted connections requiring high-temperature anti-seize protection.
• Heat-resistant steel fasteners: Screws, nuts and bolts manufactured from suitable heat-resistant alloys.
• Nickel-based alloys: Specified threaded connections where the product’s material and application requirements are satisfied.
• Industrial flanges: Suitable bolted connections in high-temperature process equipment.
• Engine and exhaust-related connections: Applications where the fastener material, temperature and lubricant requirements are compatible.
• Industrial maintenance and assembly: Fasteners that require controlled assembly lubrication and later nondestructive disassembly.

These examples do not mean that the paste is suitable for every connection within these equipment categories. Verify the component manufacturer’s lubrication requirements and the current technical data sheet before application.

Technical Characteristics

MOLYKOTE P-37 is a grey-black anti-seize paste with a mineral-oil carrier and solid lubricants. The manufacturer lists a service temperature range of −30°C to +1,400°C for the product’s stated application and solid-lubricant temperature resistance.

Published typical properties include a density of approximately 1.21 g/cm³ at 20°C, an unworked penetration of 280–310 (0.1 mm), a four-ball weld load of 5,500 N and maximum specified sulfur and total-halogen levels of 250 ppm and 200 ppm, respectively.

These values are typical technical data and should not be treated as guaranteed acceptance limits. Consult the current manufacturer technical data sheet for the test methods and full product requirements.

Application and Handling Instructions

Clean and degrease the fastener and application area before applying the paste. Remove rust or deposits from the threads with an appropriate wire brush where permitted by the equipment maintenance procedure. Apply a controlled, even coating to the specified contact surfaces.

Do not mix MOLYKOTE P-37 with other lubricants. Follow the equipment manufacturer’s tightening torque, preload and assembly instructions. Using an anti-seize paste can change friction during tightening, so do not automatically reuse torque values specified for dry or differently lubricated fasteners.

Read the current product label and Safety Data Sheet before handling. Wear the protective equipment specified in the SDS and follow the manufacturer’s storage and disposal guidance.

Why Choose the 1 Kg Pack?

A 1 kg pack may suit industrial maintenance teams and workshops that require a larger quantity of anti-seize paste than a small maintenance container.

However, the manufacturer’s official product page lists standard sizes including a 500 g can, 25 kg pail and 180 kg container, rather than a standard 1 kg can. Confirm that your supplier can provide a genuine, correctly labelled 1 kg pack before publishing this exact pack size.
