ND Microspheres TA is a process in which dual microencapsulated, room temperature curing threadlockers are applied to male or female threaded fasteners of virtually all sizes, configurations, materials and finishes. Dual microencapsulation results in a threadlocker which is less susceptible to environmental conditions. Pre-applied ND Microspheres TA fasteners arrive dry to the touch and ready for assembly.
After choosing ND Microspheres TA processing, have your parts sent to one of ND’s service centers. ND will then apply a microencapsulated activator and resin in a binder solution. This material dries on the part and is then shipped back to the customer for use. When installed, the shearing forces caused by engagement with a mating part release the activator and resin, allowing them to mix. The resulting chemical reaction rapidly bonds the surfaces, locking the parts together and sealing leak paths.
ND Microspheres TA processing is compatible with most fastener sizes, configurations, materials and finishes.
ND Microspheres TA processing is available in three formulas to meet differing needs including; low strength, high strength, and high temperature with torque tension control.
A cross-linked molecular structure makes TA Series materials some of the most resistant types of adhesives. Oil, gasoline, salt spray, acids, solvents, and water have virtually no effect on parts after final cure.
ND Microspheres TA Series processed fasteners assemble easily with common hand tools.
Parts processed with ND Microspheres TA have an on part life of 4 years* and will remain inert until a cure is activated by engagement with a mating thread.
ND Microspheres TA processed fasteners meet or exceed all torque requirements of IFI 125, IFI 525, as well as automotive adhesive coated fastener performance specifications.
