Tec-Bond® 235 & 251 Pre-Applied Fastener Adhesives and Threadlockers
- Tectorius Tec-Bond® 235 and Tec-Bond® 251 may be replacements for 3M™ Fastener Adhesive 2353 and 3M™ Fastener Adhesive 2510, respectively. Read about it here.
- The Tec-Bond® pre-applied family of fastener adhesives and threadlockers contain microencapsulated reactive elements that are suspended in a quick-curing resin, and carried in a solvent or water medium, depending on formula.
- Tec-Bond can be applied to male or female threaded fasteners of virtually all sizes, configurations, compositions and finishes and require no heat or primers for curing.
The shearing forces caused by installation of the fastener to the mating part release reactive compounds that cure into a tough, well bonded polymer. The resulting matrix rapidly bonds the surfaces, semi-permanently locking parts together and sealing leak paths.

DESCRIPTION:
Tec-Bond 235 Series of thread locking products are room-temperature curing, microencapsulated adhesives, while Tec-Bond 251 is a high-temperature resistant, microencapsulated adhesive. They can be applied to male or female threaded fasteners of virtually all sizes, configurations, compositions and finishes.
Tec-Bond 235 & 251 contain microencapsulated reactive elements that are suspended in a quick-curing resin, carried in a solvent medium.
The shearing forces caused by installation of the fastener to the mating part release reactive compounds that cure into a tough, well-bonded polymer. The resulting matrix rapidly bonds the surfaces, semi-permanently locking parts together and sealing leak paths.
Tec-Bond 235 & 251 offer consistent and predictable torque values, and requires no heat or primers for curing.
Tectorius is proud to present water-based versions of Tec-Bond 235 and Tec-Bond 251: Tec-Bond 240-IN and Tec-Bond 261-IN, respectively. Click here to learn more about these environmentally friendly alternatives.
TEC-BOND BOOSTER:
Introducing our new and improved booster that comes with every order of Tec-Bond 235 and 251. Proper addition of booster increases performance torque 100-200%!
PRODUCT FEATURES:
» Unaffected By Automotive Fluids: Tec-Bond 235 & 251 resist and seal against most automotive fluids: oil, water, antifreeze, and gasoline have virtually no effect once final cure has been achieved. Tec-Bond 251 is designed to function in high-temperature environments for extended periods of time, such as in engine compartments.
» Variety of Strengths, Colors, & Viscosities: these products are available in a variety of colors (for easy part inspection) and formulas to best suit the customers’ coating equipment. A wide range of similar Tec-Bond products are formulated to satisfy most thread locking requirements.
» Fast Fixture Times: Under typical conditions, fixture is achieved within 90 minutes.
» Saves Money: Tec-Bond 235 & 251 save valuable time and are less expensive than applying bottled thread locking compounds at the point of assembly.
» Suitable for Production Coating: Tec-Bond 235 & 251 are available in viscosities suitable for use on a broad range of production coating equipment.
