- 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.
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.
