2026 Best Threadlocker Manufacturer in China

As a world-leading threadlocker manufacturer and premium threadlocker supplier, Quanzhou Jingu New Material Technology Co., Ltd. (Jingu) specializes in providing high-performance anaerobic threadlockers for automotive, industrial machinery, hydraulic systems, and electronic appliance sectors. Our single-component, room-temperature curing threadlocking adhesive is specially engineered for metal fasteners up to M36, delivering reliable anti-loosening, leak-proof sealing, and exceptional resistance against severe vibration and chemical corrosion for B2B industrial buyers worldwide.

20 Years Source Threadlocker Factory

Established on March 15, 2006, Quanzhou Jingu New Material Technology Co., Ltd. is a source manufacturer boasting 20 years of expertise in industrial adhesive R&D and production. As a well-known enterprise in China's specialty adhesive industry, Jingu has continuously driven innovation and development in polymer bonding technologies.

To fulfill large-scale procurement demands from global buyers, Jingu has established robust manufacturing advantages:

• Modern Production Base: Operates a standardized 10,000 square meter industrial facility enabling centralized, large-scale production management.
• Professional Talent Team: Staffed with over 100 skilled production workers and a dedicated team of more than 30 R&D technicians.
• Robust Annual Output: Maintains an annual production capacity of 256 tons of anaerobic adhesives to ensure on-time delivery during peak seasons.
• Global Business Network: Products are highly acclaimed in domestic automotive and machinery sectors while exporting to over 150 countries and regions.

Engineered to solve fastener loosening issues in heavy machinery and high-speed equipment, Jingu's anaerobic threadlocker replaces traditional mechanical washers and spring gaskets. By filling microscopic thread gaps and excluding air, the liquid adhesive rapidly cures under metal catalysis into a high-strength polymer layer, permanently preventing vibration looseness and fluid leaks.

Jingu Threadlocker Product Advantages

Formulated with premium acrylate as its main raw material, Jingu anaerobic threadlocking adhesive features a single-component, room-temperature curing design for permanent locking and sealing of metal fasteners up to M36. The product offers the following distinctive advantages:

• Convenient Single-Component Application: Requires no complex mixing ratios; ready to apply straight from the bottle, substantially boosting automated assembly and repair efficiency.
• Rapid Curing & High Strength: Achieves initial fixture in approximately 20 minutes at 25°C and 100% full cure within 24 hours, completely filling thread gaps to form a shock-resistant, high-shear barrier.
• Wide Temperature Range: Operates effectively between -54°C to 150°C, withstanding extreme heat, severe cold, and harsh thermal cycling.
• Superior Chemical Resistance: Cures into a tough polymer matrix that resists engine oil, hydraulic fluid, diesel, water, and mild acids or alkalis.

ISO System Certification and Leak-Proof Quality

As a trusted threadlocker supplier for industrial clients worldwide, Jingu puts quality management and standardization at the forefront of its operations:

• Authoritative Dual ISO Certifications: Fully certified under ISO9001 Quality Management and ISO14001 Environmental Management systems for safe and compliant production.
• Three-Stage Quality Control: Enforces strict Incoming Quality Control (IQC), In-Process Quality Control (IPQC), and Outgoing Quality Control (OQC) to guarantee 100% factory pass rates.
• 100% Gap Filling & Seamless Sealing: Excellent fluidity fills microscopic surface irregularities completely, acting as a liquid gasket to prevent oil, gas, and moisture leakage.
• Outperforms Mechanical Fasteners: Tested under continuous high-pressure vibration in hydraulic systems and automotive engines, exceeding traditional spring washers in sealing pressure and vibration resistance.

Automated Line and Precision Manufacturing

As a professional threadlocker manufacturer, Jingu recognizes that advanced equipment and strict process control are essential to ensuring batch-to-batch consistency. Our 10,000 m² factory houses automated manufacturing lines:

• Digital Reactor Agitation: Computerized systems monitor acrylate monomer premixing, initiator dosing, and vacuum homogenization in real time to eliminate micro-bubbles and impurities.
• Batch-to-Batch Stability: Precise temperature and mixing speed controls ensure consistent viscosity, thixotropy, and breakaway torque parameters across every production lot.
• High-Precision Filling: Automated volumetric filling equipment minimizes fill volume errors while increasing assembly throughput.
• Special Breathable PE Packaging: Uses specialized air-permeable polyethylene (PE) bottles that retain necessary oxygen inside the container, preventing premature gelation and extending shelf life.
