Name: Tec-Lok™ 130 Series
Brand: Tectorius

Tec-Lok™ 130 Series is a resilient locking patch applied to the threaded portion of fasteners to prevent unintended loosening and promote sealing across an exceptional operational temperature range of -150°C to 371°C(-238°F to 700°F). Built on a proprietary polymer formula, it replaces standard nylon patch in applications where thermal extremes would cause conventional materials to fail.

This non-reactive thread locker is intended for parts that must remain serviceable and removable while withstanding most fluids, solvents, and harsh environments. Unlike competing high-temperature patch products,Tec-Lok™ 130 Series requires part heating to only 250°C (418°F) for application, which protects plating, surface finishes, and heat treatment from damage.

Operational temperature range of -150°C to 371°C (-238°F to 700°F) covers both ultra-high and cryogenic environments.
Proprietary polymer formula replaces standard nylon where thermal performance is required.
Patch coverage ranges from 90 to 360 degrees; 360-degree application provides maximum locking security and sealing.
Outstanding color stability even at extreme temperatures.
Available in liquid (water-based and solvent-based) and powder grades with multiple color options.
More than 5 on-off cycles support serviceability and field maintenance.

Automotive: High-heat fastener assemblies on engine, exhaust, and powertrain components.
Industrial Manufacturing: Equipment and machinery operating at sustained elevated temperatures.
Industrial Maintenance and Repair: High-temperature field service assemblies requiring serviceable and removable fasteners.
Cryogenic and Extreme Environment Applications: Assemblies exposed to semi-cryogenic temperatures as low as -150°C (-238°F).
Aerospace, Aeronautics: Fastener assemblies on aircraft and propulsion systems requiring reliable retention across extreme thermal cycling and high-vibration environments.

Performance, Advantages and Benefits

Proprietary High-Temperature Polymer Formula: Delivers reliable thread locking and sealing across an operational range of-150°C to 371°C (-238°F to 700°F), far exceeding the thermal limits of standard Nylon 11 patch. The formula maintains mechanical integrity and color stability at temperatures that would degrade conventional locking patch materials.

Low Application Temperature: Despite its extreme-temperature performance, Tec-Lok™ 130 Series requires part heating to only 250°C (418°F) for application. This protects plating, decorative finishes, and heat-treated surfaces from damage during the coating process, an advantage over competing high-temperature patch products that require higher application temperatures.

Flexible Grade Selection: Available in water-based liquid, solvent-based liquid, and powder grades, the 130 Series can be matched to a wide range of application equipment and process requirements. Multiple color options support part identification and brand differentiation.

Broad Chemical and Environmental Resistance: Excellent resistance to chemicals, corrosion, and harsh environments ensures patch integrity across the full operational temperature range, including exposure to fluids, solvents, and salt spray conditions.

What makes Tec-Lok™ 130 Series different from the 100 Series?

The 130 Series uses a proprietary polymer formula in place of standard nylon. This allows it to perform at operational temperatures from-150°C to 371°C (-238°F to 700°F), well beyond the -56°C to 121°C (-70°F to250°F) range of the Tec-Lok 100 Series. It is the appropriate choice when fastener assemblies are exposed to extreme heat, cold, or both.

What is the application temperature for Tec-Lok™ 130 Series?

Parts must be heated to 250°C (418°F) for the patch to be applied. This is lower than many competing high-temperature patch products, which reduces the risk of damage to plating, surface finishes, and heat treatments during the coating process.

How many reuse cycles does Tec-Lok™ 130 Series support?

More than 5 on-off cycles are supported. For applications requiring higher reusability, Tec-Lok™ 100 Series supports up to 15 cycles under standard temperature conditions.

Does Tec-Lok™ 130 Series perform in cryogenic environments?

Yes. The 130 Series is rated for operational temperatures as low as -150°C (-238°F), making it suitable for semi-cryogenic applications where standard nylon patch would lose flexibility or fail.

What color options are available for the 130 Series?

Liquid grades (130, 133, 134) are available in yellow, red, green, blue and black. Powder grades (135-139) are available as dedicated single-color grades: yellow (135), green (136), blue (137), red (138), and black (139). Custom colors may be available; contact Tectorius for details.
