Anaerobic Adhesive

LINGWO Anaerobic Adhesives: The Invisible Guardian for Thread Locking & Sealing

I. Product Core Positioning: Cures in Silence, Forging Unshakeable Connections

In modern industrial equipment characterized by high-speed operation and constant vibration, the loosening of a single screw can lead to the failure of an entire machine. The LINGWO Anaerobic Adhesive series is specifically engineered to address this fundamental challenge. It is an intelligent engineering material that cures automatically in the absence of air (e.g., between engaged thread surfaces) upon contact with metal ions. It serves as an innovative solution to replace traditional mechanical locking methods (like lock washers), achieving permanent anti-loosening, sealing, and retaining.

As experts in bonding and sealing, LINGWO deeply understands the diverse needs—from heavy machinery to miniature electronics—for thread-locking strength, removability, and chemical resistance. We offer a complete portfolio of anaerobic adhesives across all strength grades: from medium/low strength for serviceable disassembly to high strength for permanent locking, and specialized formulas for pipe thread sealing. We not only provide standard products but can also offer customized formulations based on your substrate metal type, gap size, cure speed, and temperature resistance requirements, ensuring every threaded connection remains as solid as new.

II. Core Technical Advantages & Product Series

1. Unique Curing Mechanism & User-Friendly Process

• Oxygen-Activated, Precise Curing: Cures only in the absence of air within tightly mated metal interfaces like threads and flanges, preventing residue in non-target areas and enabling clean, precise locking and sealing.

• Single-Component, No Mixing Required: Ready to use directly from the bottle for drop or spray application, greatly simplifying inventory management and field operations, boosting assembly efficiency.

• Room-Temperature Cure, Rapid Strength Buildup: Cures rapidly at room temperature catalyzed by metal ions, providing effective resistance to rotation early on, meeting continuous assembly needs.

2. Exceptional Locking & Sealing Performance

• Superior Anti-Loosening & Vibration Resistance: Once cured, forms a tough thermoset plastic that completely fills thread clearance, effectively resisting loosening and wear caused by vibration and shock, offering reliability far exceeding mechanical fasteners.

• Excellent Sealing & Leak Prevention: Fully fills microscopic voids between thread pairs, forming a positive seal that effectively prevents leakage of water, oil, fuel, gas, and various chemicals.

• Broad Gap-Filling Capability: Formulations with different viscosities and thixotropy are designed to accommodate locking and sealing needs from tight fits to larger gaps (typically up to 0.25mm).

3. Professional Series by Strength & Function

• Low/Medium Strength Removable Series: Provides sufficient locking force to prevent vibration-induced loosening while allowing disassembly with standard tools, facilitating equipment maintenance, calibration, and repair. Widely used in components requiring regular service.

• High Strength Permanent Locking Series: Creates very high-strength locking, effectively “welding” threads together. Suitable for critical load-bearing parts, safety devices, and permanent assemblies not intended for disassembly.

• Pipe Thread Sealing Series: Specifically designed for sealing metal pipe thread joints, featuring good pressure and chemical resistance. Can replace PTFE tape for a cleaner, more reliable, and precisely controlled seal.

• Pre-applied Micro-encapsulated Series: Features anaerobic adhesive pre-applied onto screws or nuts in a dry, non-tacky micro-encapsulated layer. Capsules rupture during tightening, releasing the adhesive for curing. Enables automated assembly and great process consistency.

4. Outstanding Environmental Resistance & Material Compatibility

• Excellent Chemical & Temperature Resistance: Once cured, resists various lubricants, fuels, solvents, and chemicals, with a wide operating temperature range (typically -55°C to 150°C, special grades available for higher).

• Broad Metal Compatibility: Suitable for most active metals like steel, stainless steel, aluminum, copper, and zinc. For non-active or passive surfaces (e.g., some stainless steels, chrome plating, passivated surfaces), dedicated primers ensure reliable curing.

III. Typical Application Scenarios

• Automotive & Transportation: Engine bolt locking, transmission fastener securing, wheel bearing retaining, fuel line joint sealing, chassis component anti-loosening.

• Industrial Equipment & Heavy Machinery: Hydraulic system pipe joint sealing, bearing & bushing retaining/sealing, stamping die screw securing, fan & pump fastener locking.

• Electronics, Electrical & Appliances: Servo motor housing screw locking, large heatsink installation, anti-loosening for internal moving parts in appliances (e.g., washing machine counterweights), power module fastening.

• Energy & Infrastructure: Wind turbine gearbox bolt locking, auxiliary sealing for petrochemical pipeline flanges, supplementary anti-loosening for high-strength bolted connections in steel structures.

• Maintenance, Repair & Overhaul (MRO): An essential tool for preventive maintenance and on-site repair, used for fixing loose fasteners, repairing worn threads, and on-site leak sealing.
