Import Black Moly Grease, Anti-Seize Compound For Threads — Buy in wholesale FOB from Supplier in China

Black Moly Grease is a thread anti-seize compound formulated with molybdenum disulfide (MoS2) and graphite suspended in a mineral oil base with inorganic thickener, designed to prevent galling, seizing, and fretting corrosion in threaded fasteners subjected to extreme pressure and elevated temperature. This product from Dongguan Vnovo New Technology Co Ltd, based in Dongguan, Guangdong Province, China, is positioned for industrial maintenance, mining equipment servicing, and construction machinery applications where torque consistency and future disassembly are critical. The formulation tolerates continuous operating temperatures up to 400°C, placing it in the high-temperature thread lubricant category alongside copper-based and nickel-based anti-seize variants. The mineral oil and inorganic thickener base provides moderate water washout resistance compared to synthetic polymer-thickened alternatives.

The molybdenum disulfide component functions as a solid-film lubricant through lamellar shear between its crystalline S-Mo-S layers, reducing the coefficient of friction to 0.05-0.1 under boundary lubrication conditions where liquid lubricants fail. Graphite additive complements this with oxidation-resistant lubrication above 350°C where MoS2 begins to degrade in air. The inorganic thickener, likely bentonite or silica-based given the temperature ceiling, provides structural stability without the melting point limitations of lithium or calcium soap thickeners. Standard industry formulations for this class of anti-seize typically contain 35-45 percent solids content by weight, with particle size distribution critical to thread fit and torque-tension correlation. Users should verify whether this product contains metallic zinc, copper, or aluminum powders sometimes added for additional extreme-pressure performance, as these can cause galvanic corrosion with certain fastener materials.

Primary applications include cylinder head bolts, exhaust manifold studs, turbine casing fasteners, and heavy equipment track pad bolts where thermal cycling and vibration promote thread damage. Mining operations use similar compounds on crusher frame bolts and dragline bucket fasteners exposed to abrasive dust and high preload stresses. Construction equipment manufacturers specify anti-seize on telescopic boom pivot bolts and undercarriage fasteners requiring periodic adjustment. Buyers of this Dongguan-sourced product should confirm with the supplier the exact solids content, base oil viscosity at 40°C, and whether the formulation meets specific OEM specifications such as Caterpillar, Komatsu, or generic ASTM D2596 weld point requirements. Packaging options for export typically range from 1 kg cans to 180 kg drums; bulk buyers should clarify minimum order quantities and whether the supplier offers custom labeling with hazard communication standards for destination markets.

Dongguan Vnovo New Technology Co Ltd operates from Dongguan in Guangdong Province, China, a manufacturing hub with extensive industrial chemical and lubricant blending capacity. The supplier holds an organic-tier designation with harbor-tier trust status, indicating a verified business entity with platform identity confirmation but limited transactional history or buyer feedback visibility. No response rate or average response time data is available in the source profile. The company name structure suggests focus on novel technology applications, though no patent portfolio, R&D expenditure, or technical staffing details are disclosed.

The listing positions Dongguan Vnovo as a direct manufacturer or formulated-product trader of specialty lubricants for industrial maintenance markets. No information is provided regarding facility certifications such as ISO 9001 or ISO 14001, production capacity, quality control laboratory capability, or key account relationships. The absence of response metrics and the organic-tier status suggest buyers should conduct enhanced due diligence including factory audit, sample testing against specification, and reference checks with existing export customers before committing to volume orders. The supplier's location in Dongguan provides access to Shenzhen and Guangzhou port infrastructure for international shipment.
