ND Microspheres® 1193
Technical Data Sheet

Performance of Cured Material

Product Description
ND Microspheres® 1193 is a powerful pre-applied adhesive film forlocking and sealing. ND Microspheres 1193 is factory pre-applied toeither internal or external threads. It remains inert on the fastener until
assembly of the threads mixes the resin. The resin fills the voids of thethreads and cures to lock and seal the assembly. ND Microspheres
1193s and 1193sN are designed to perform at room temperature andunder continuous service temperatures up to 149°C (300°F) orintermittently up to 204°c (400°F).

Please note that installation, breakaway, and prevailing off-torque data
are from test results conducted on an M-10 x 1.5 class 10.9 zincorganic finish bolts and M010 x 1.5 class 10 zinc nuts. Performance
may vary depending on fastener finish.

Heat age testing was conducted on M-10 x 1.5 zinc organic finish bolts
and zinc plate nuts. Assembled fasteners were aged at 150°C for 168
hours and allowed to cool to room temperature before breakaway test.
Immersion testing was conducted using M-10 x 1.5 Zinc organic finish
bolts and zinc plate nuts. Assembled fasteners were submerged in each
fluid for 168 hours at the temperature. Assemblies were allowed tocool to room temperature before breakaway test.

General Information
Storage
Fasteners coated with product are to be stored in a cool and drylocation at temperatures between -10°C to 35°C. Optimal storage is25±4°C with 50% or below relative humidity.
