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 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.
