Description
BORN2BOND™ PA-WL Anaerobic Adhesive: oil-tolerant thread sealing
The BORN2BOND™ PA-WL anaerobic adhesive is designed for threaded assemblies exposed to oil. It cures in the absence of air and ensures a durable thread seal, even on contaminated surfaces.
Its oil-tolerant formula eliminates the need for systematic degreasing before application. A real time-saver in maintenance and production.
Resistant to vibrations and industrial fluids, it protects assemblies against loosening and leaks in the long term.
What is BORN2BOND™ PA-WL and how does it work?
The BORN2BOND™ PA-WL is an anaerobic thread-locking adhesive developed by Forgeway. Its unique feature: it is formulated to adhere and cure even on surfaces contaminated by oil.
It provides sealing and locking for threaded assemblies, hydraulic fittings, industrial bolts, piping, where the presence of lubricants or cutting fluids makes conventional adhesives ineffective.
Anaerobic curing principle: why this adhesive hardens without air
Anaerobic adhesives remain liquid in the presence of oxygen. As soon as the adhesive is confined between two metal surfaces, air is excluded and curing is triggered.
Metal ions (iron, steel, brass) act as catalysts. The reaction transforms the resin into a rigid and resistant polymer that fills the gaps in the thread.
PA-WL incorporates a special formulation that allows it to tolerate residual oil films. Where a standard anaerobic adhesive would see its adhesion compromised, PA-WL maintains complete and homogeneous curing.
Result: a leak-proof threaded joint, resistant to vibrations and fluids, without systematic degreasing of the part before application.
Technical characteristics and performance of BORN2BOND™ PA-WL
The BORN2BOND™ PA-WL is a high-performance anaerobic adhesive formulated for sealing and locking threaded assemblies, even in the presence of oil.
Its oil tolerance distinguishes it from conventional anaerobics. Where a standard adhesive fails on a contaminated surface, PA-WL grips and cures correctly.
It is suitable for metal threads exposed to harsh industrial environments: lubricants, cutting oils, light greases. Ideal for maintenance under real conditions, without prior systematic cleaning.
Curing is anaerobic: it is triggered in the absence of oxygen, between contact metal surfaces. Result: a solid joint, resistant to fluids and gases, resistant to vibrations.
| Product | Oil tolerance | Application type | Temperature resistance | Typical usage |
|---|---|---|---|---|
| BORN2BOND™ PA-WL | ✔ Yes | Thread / sealing | Up to ~150 °C | Industrial maintenance, oily surfaces |
| Loctite 577 | ✘ No | Thread / sealing | Up to 150 °C | Clean surfaces, fine threads |
| Loctite 55 (cord) | ✔ Partial | Thread / sealing | Up to 130 °C | Plumbing, gas, quick assembly |
| BORN2BOND™ PA-M | ✘ No | Thread / locking | Up to ~150 °C | Clean threaded assemblies, mechanical resistance |
At Dagobert Industrie, we recommend PA-WL for any maintenance intervention where complete degreasing of parts is not feasible.
Its adapted viscosity facilitates application on both fine and coarse threads. The adhesive penetrates well into the gaps without excessive overflow.
BORN2BOND™ PA-WL vs. other anaerobic thread sealants: comparison table
Comparison with Loctite 577, ThreeBond 1305 and other market references
The market for anaerobic thread-locking adhesives is full of references. Here is how BORN2BOND™ PA-WL compares to the most widely used products in the industry.
| Product | Manufacturer | Oil tolerance | Dismantling resistance | Max temperature | Typical application |
|---|---|---|---|---|---|
| BORN2BOND™ PA-WL | Intertronics / BORN2BOND | ✅ High (oily surfaces) | Medium (removable) | 150 °C | Oily threads, hydraulics, mechanics |
| Loctite 577 | Henkel | ⚠️ Low to moderate | Medium (removable) | 150 °C | Clean threads, gaseous and liquid fluids |
| Loctite 243 | Henkel | ⚠️ Moderate | Medium (removable) | 150 °C | Standard screws, general use |
| ThreeBond 1305 | ThreeBond | ⚠️ Low | Low to medium | 120 °C | Light threads, low-stress assemblies |
| Loctite 5188 | Henkel | ✅ Good | High (difficult to remove) | 150 °C | Flat seals, flanges, not suitable for fine threads |
The PA-WL clearly stands out on a key point: its ability to cure on surfaces contaminated with oil, where most conventional anaerobics fail or require prior degreasing.
Unlike Loctite 577, it does not require a perfectly clean surface. The time savings in the workshop are real, especially on hydraulic circuits or equipment under maintenance.
Compared to ThreeBond 1305, PA-WL offers better temperature stability and superior chemical resistance to common industrial fluids.
At Dagobert Industrie, we recommend BORN2BOND™ PA-WL whenever systematic degreasing is not possible or too restrictive in your process.
Typical applications and fields of use for BORN2BOND™ PA-WL
The BORN2BOND™ PA-WL is designed for locking and sealing threaded assemblies in the presence of oily contamination. This is its preferred domain.
It is aimed at industrial environments where perfectly cleaning every part before bonding is neither practical nor realistic. No need for extensive degreasing: the adhesive works even on oiled surfaces.
Here are the most common applications:
- Hydraulic and pneumatic fittings: threaded sealing on pressurized circuits
- Engines and gearboxes: plugs, drain screws, threaded sensors exposed to engine oil
- Industrial maintenance equipment: field repairs, without prior cleaning
- Machine tool assemblies: screw locking in lubricated zones
- Automotive and heavy-duty industry: threaded components in contact with cutting fluids or transmission oils
It is suitable for both production assembly and on-site maintenance and repair operations.
| Product | Oil tolerance | Main use | Dismantling resistance |
|---|---|---|---|
| BORN2BOND™ PA-WL | ✔ Yes (oiled surfaces) | Thread sealing and locking | Medium to high |
| Loctite 243 | Partial (degreasing recommended) | General thread locking | Medium |
| Loctite 577 | Limited | Fine thread sealing | Low to medium |
| Permabond LH050 | ✔ Yes | Thread locking on oiled surfaces | Medium |
At Dagobert Industrie, we recommend PA-WL as soon as parts arrive lubricated at the workshop and preparation time is limited.
Instructions for use and application tips for BORN2BOND™ PA-WL
The BORN2BOND™ PA-WL is an anaerobic adhesive designed for sealing threaded assemblies in the presence of oil. Its application requires a few simple precautions to ensure optimal curing.
Surface preparation
PA-WL tolerates lightly oiled surfaces, which distinguishes it from standard anaerobics. However, wipe off excess oil with a clean cloth before application.
On passive or low-activity metals (stainless steel, aluminum, zinc), the use of an anaerobic activator is highly recommended. It accelerates curing and improves the final strength.
Surfaces must be free of chips, rust, and coarse dirt. A quick cleaning with acetone or isopropyl alcohol remains the best practice on clean metal.
Curing time and application precautions
Apply a few drops of PA-WL directly onto the bolt thread or into the tapped hole. Any excess that emerges from the assembly can be wiped off immediately.
Handling strength is reached in 10 to 30 minutes at room temperature. Complete curing generally takes 24 hours.
Avoid applying the adhesive to hot parts (above 150 °C). Anaerobic curing requires the absence of oxygen: the assembly must be performed immediately after application.
