Anaerobic Adhesive BORN2BOND™ TA-WL

BORN2BOND™ TA-WL anaerobic adhesive: threadlocker with no CLP substances, oil-tolerant

The BORN2BOND™ TA-WL is an anaerobic threadlocker designed for oily environments: it polymerizes even in the presence of residual oil on parts.

Its formulation is free of CLP substances (no CMR, no endocrine disruptors), which simplifies risk management in the workshop.

It locks and secures threaded assemblies against vibration and loosening, while remaining removable with standard tools.

What is BORN2BOND™ TA-WL and how does it work?

The BORN2BOND™ TA-WL is an anaerobic threadlocking adhesive developed by Ineos Composites. It locks and secures threaded assemblies by preventing any involuntary loosening due to vibration or shock.

Its special feature: it is formulated without CLP-classified substances (no health-related hazard pictograms) and remains effective on lightly oiled surfaces. This is a direct advantage on construction sites or in workshops, where parts are not always perfectly degreased.

Anaerobic polymerization principle: why this glue cures without air

An anaerobic adhesive remains liquid as long as it is in contact with oxygen in the air. As soon as it is confined between two metal surfaces, the oxygen is excluded and polymerization is triggered.

The metal ions present on the surface of the parts (steel, stainless steel, brass...) act as reaction catalysts. The adhesive goes from a liquid state to a solid thermosetting polymer, filling all thread gaps.

Result: a continuous molecular seal between the threads, resistant to vibration, fluids, and temperature variations. Removal remains possible with tools, which distinguishes it from a permanent threadlocker.

At Dagobert Industrie, we offer TA-WL for applications where regulatory safety (REACH, CLP) and oil tolerance are non-negotiable criteria.

Technical characteristics and performance of BORN2BOND™ TA-WL

The BORN2BOND™ TA-WL is an anaerobic threadlocking adhesive developed by Indevio (formerly Bostik Advanced Adhesives). It is distinguished by two key features: a formulation with no CLP substances (no danger classification according to European regulation) and high oil tolerance.

Concretely, it polymerizes in the absence of air, directly on threaded assemblies, even when lightly oiled. No need to perfectly degrease the part before application.

Here are its main characteristics:

• Removal resistance: medium strength, disassembly possible with tools
• Oil tolerance: polymerizes on oily surfaces without primer
• No CLP substances: no danger labeling, simplified handling
• Service temperature: up to approximately 150 °C
• Handling time: approximately 10 to 20 minutes depending on the substrate
• Chemical resistance: oils, fuels, hydraulic fluids

Compared to a standard threadlocker like Loctite 243, TA-WL offers a more favorable toxicological profile thanks to the absence of CLP classification, which facilitates its use in regulated environments (food processing, medical, light maintenance).

Characteristic	BORN2BOND™ TA-WL	Loctite 243	Loctite 270
Type	Anaerobic threadlocker	Anaerobic threadlocker	Anaerobic threadlocker
Locking strength	Medium	Medium	High
No CLP substances	Yes	No	No
Oil tolerance	Yes	Limited	Limited
Tool-based removal	Yes	Yes	Difficult
Max. temperature	~150 °C	~150 °C	~150 °C

TA-WL is therefore the logical choice when internal regulations limit products classified as hazardous or when parts arrive in the workshop without prior degreasing.

BORN2BOND™ TA-WL vs. other anaerobic threadlockers: comparative table

Comparison with Loctite 272, Loctite 271 and other market references

The market for high-strength anaerobic threadlockers is dominated by a few well-known references. Here is how the BORN2BOND™ TA-WL stands up to the competition.

Product	Manufacturer	Strength	Oil tolerant	No CLP substances	Max. temp.	Typical usage
BORN2BOND™ TA-WL	Intertronics / BORN2BOND	High	✅ Yes	✅ Yes	150 °C	Oily threads, regulated environments
Loctite 271	Henkel	High	❌ Limited	❌ No	150 °C	Clean threads, general purpose
Loctite 272	Henkel	High	❌ Limited	❌ No	200 °C	Clean threads, high temperatures
Loctite 2701	Henkel	Very high	❌ No	❌ No	150 °C	Fine threads, treated steel
Permabond A130	Permabond	High	⚠️ Partial	❌ No	150 °C	Standard metal threads

The TA-WL stands out on two key points: its oil tolerance and the absence of substances subject to CLP regulation.

Concretely, Loctite 271 and 272 require degreased surfaces to polymerize correctly. TA-WL, however, adheres even on lightly oiled threads, without pre-treatment.

The formulation without CMR or endocrine disruptors of TA-WL meets the growing requirements of the food, medical, or pressure equipment sectors. It is a real advantage where other products are blocked by regulation.

Typical applications and areas of use for BORN2BOND™ TA-WL

The BORN2BOND™ TA-WL is an anaerobic threadlocking adhesive designed for demanding environments where industrial lubricants and oils are omnipresent. Its oil-tolerant formulation allows it to polymerize even on slightly contaminated surfaces, without systematic degreasing.

It is intended for screwed assemblies exposed to hydraulic fluids, cutting oils, or motor oils. It is a concrete advantage on production lines or in maintenance, where perfect cleaning is not always possible.

Its formulation is free of CLP-classified substances (no CMRs, no SVHCs). It meets growing safety requirements in industry, particularly for applications in contact with operators or in indirect food environments.

Typical application areas:

• Industrial maintenance on machine tools and hydraulic equipment
• Screwed assemblies in the automotive industry and commercial vehicles
• Agricultural equipment and construction machinery (frequent oily environments)
• Fasteners on compressors, pumps, and gearmotors
• Applications requiring enhanced toxicological compliance

Compared to a standard anaerobic threadlocker like Loctite 243, TA-WL offers superior oil tolerance without requiring an activation primer on passive metals. It remains removable with tools, which facilitates routine maintenance interventions.

Instructions and application tips for BORN2BOND™ TA-WL

The BORN2BOND™ TA-WL is applied directly to the screw thread, even in the presence of oil traces. No need for thorough degreasing before application.

Place a drop on the male thread, on the screw head side. The product distributes itself during tightening. One drop is sufficient for threads up to M20.

Curing starts immediately upon assembly, in the absence of air and upon contact with metal. Removal resistance is reached in 10 to 30 minutes depending on ambient temperature.

Full strength is achieved after 24 hours at room temperature. Below 15 °C, opt for a longer cure time or use an activator to accelerate polymerization.

For disassembly, apply localized heat to approximately 250 °C. Standard tools are then sufficient to unscrew without damaging the parts.

A few best practices at Dagobert Industrie:

• Clean parts of chips and solid residues before application (residual oil is tolerated)
• Avoid very cold surfaces: warm the parts if the workshop is below 10 °C
• Close the bottle immediately after use to avoid premature polymerization
• Do not use on plastic threads or non-activated passive materials

TA-WL is suitable for threaded assemblies exposed to oily fluids: machine tools, hydraulic equipment, industrial production lines.

FAQ - BORN2BOND™ TA-WL

1. What differentiates TA-WL from a classic threadlocker?

The BORN2BOND™ TA-WL is formulated without CLP substances (carcinogenic, mutagenic, reprotoxic). Most traditional anaerobic threadlockers contain CLP-classified monomers, which imposes strict regulatory constraints in an industrial setting.

2. Is it really effective on oiled parts?

Yes. TA-WL is designed to tolerate the presence of oil on surfaces to be assembled. It polymerizes correctly even on slightly soiled threads, without prior systematic degreasing.

3. On what types of threads can it be used?

It is suitable for common metal threads: steel, stainless steel, brass. It is adapted to screwed assemblies exposed to vibration, replacing a spring washer or lock washer.

4. What removal resistance does it offer?

TA-WL offers medium resistance, which allows disassembly with tools without damaging parts. It is the right compromise for assemblies that must remain maintainable.

5. Are there surfaces or conditions where it will not work?

Like any anaerobic, it requires the absence of air between surfaces to polymerize. On inactive materials (certain plastics, passivated metals), the use of an activator may be necessary to obtain complete polymerization.

6. Why choose TA-WL instead of an equivalent Loctite product?

TA-WL meets the same uses as a Loctite 243 (medium threadlocker, oil-tolerant), but with a formulation without CLP-classified substances. For companies subject to REACH obligations or looking to reduce their chemical exposure, this is a concrete argument.
