Core Pain Point: Does your equipment suffer from severely seized bolts and threads after high-temperature, high-load operation, leading to difficult maintenance disassembly, project delays, or even component damage?
Solution: Vnovo PASTE W2 is a high-performance anti-seize paste specifically designed for extreme operating conditions. Utilizing an innovative no-drop-point formula and a metal-oxide solid lubricant system, it effectively isolates metal surfaces, preventing wear and corrosion even under sustained high temperatures up to 1100°C, ensuring safe and easy disassembly during maintenance.
1. Why is a Dedicated High-Temperature Anti-Seize Paste Necessary?
Threaded fasteners face severe challenges in high-temperature, high-load, or corrosive environments:
- Micro-welding (Cold Welding): Direct metal-to-metal contact causes material transfer under pressure and heat, leading to thread “galling” or seizure.
- Corrosion Locking: High temperatures accelerate oxidation, and corrosion products fill thread clearances, increasing disassembly torque.
- Conventional Lubricant Failure: Ordinary greases melt and flow away or carbonize after reaching their drop point, losing their protective function.
Result: Difficult disassembly, bolt breakage, and a sharp increase in labor hours and costs. PASTE W2 is born to solve these problems. It forms a stable isolating and lubricating film at the metal interface, preventing seizure at its root cause.
2. PASTE W2 Core Advantages & Specifications

Core Advantages Explained:
- ·Extremely Wide Temperature Range & No-Drop-Point Design: Ensures effectiveness from cold installation to high-temperature operation, solving the core issue of traditional grease loss at high temperatures.
- ·Metal-Oxide Lubricant System: Compared to common copper- or nickel-based anti-seize compounds, it provides an alternative high-performance solution without heavy metal concerns, especially suitable for applications sensitive to copper/nickel.
- ·Safe & Eco-friendly: Nickel- and lead-free formula reduces risks to operators and the environment, better complying with modern industrial standards.
3. Typical Applications
PASTE W2 is suitable for any threaded connections and mating surfaces exposed to high temperatures and requiring repeated disassembly:
- ·Ejector pins, guide pillars, hot runner bolts in injection or die-casting molds, preventing high-temperature seizure and extending mold life.
- ·Installation and maintenance of brake caliper guide pins, ensuring the maintainability of braking systems under high temperatures.
- ·High-temperature flange bolts, reactor bolts, kiln screws, fasteners for heat treatment equipment.
- ·Valve stems, pipe flange threads under high-temperature and high-pressure conditions.
- ·Any assembly scenario requiring prevention of thread seizure and ease of future disassembly.
4. How to Apply Correctly for Optimal Performance
1、Clean! Ensure threads or mating surfaces are dry, free of oil, dirt, rust, and old lubricant residue.
2、Apply a thin, even coating to the entire thread or mating surface; avoid excessive thickness. Coat both internal and external threads.
3、Assemble according to the specified torque procedure. Note: Using anti-seize paste changes the friction coefficient, typically allowing for a 20-30% reduction in torque. It is recommended to verify torque values under actual conditions.
4、For high-temperature, high-frequency disassembly applications, periodic inspection and reapplication are recommended.
5. Frequently Asked Questions (FAQ)
Q1: What is the maximum temperature resistance of PASTE W2? How long can it last?
A1: According to the product document, its continuous operating temperature can reach 1100°C. The specific duration depends on actual service conditions (e.g., temperature, medium, load). Testing under simulated conditions is recommended.
Q2: What exactly does “No Drop Point” mean? What are the benefits?
A2: Traditional greases melt and become liquid, flowing away when heated to their “drop point.” PASTE W2 has no defined drop point, meaning it can maintain its paste structure and adhesion for extended periods at high temperatures without softening and flowing away, which is key to its high-temperature performance.
Q3: How is it different from red copper-containing or green nickel-containing anti-seize pastes?
A3: The main differences lie in the solid lubricant and composition. PASTE W2 uses a metal-oxide system, is white in color, and is free from copper, nickel, and lead. While providing comparable high-temperature anti-seize performance, it avoids the risk of galvanic corrosion from copper or potential allergy/material restriction issues with nickel, making it a versatile and environmentally friendly alternative.
Q4: Can it be used in food or drinking water equipment?
A4: PASTE W2 is free from nickel and lead, but the product document does not specify food-grade certification. If intended for use in food, beverage, or potable water contact equipment, we strongly recommend using our company’s specialized NSF H1 certified food-grade lubricants to ensure full compliance.
