Z70: Cold Curing Superglue for Experimental Tests, and for Sensors Without High Accuracy Requirements

With its extremely fast curing time of just a minute at 20°C, superglue Z70 is popularly used in many experimental test tasks for strain gauge installation. This cyanoacrylate adhesive is also used in sensor manufacturing, although usually only if high accuracy is not required. [R1] 

Z70 cures only in very thin adhesive coatings. Since the moisture absorbed from the ambient air serves as a catalyst, the relative humidity should be about 40–70 percent. Curing of cyanoacrylates, and thus Z70, additionally depends on the adhesive surface’s chemical condition.

If the application conditions are unfavorable (e.g. low relative humidity, acidically-reacting surfaces, low temperatures), additionally using the accelerator BCY01 [R2] is recommended. A drop of this accelerator can be applied to the adhesive surface. After about a minute, the Z70 superglue can be applied.

  • Cold curing superglue: Cures very quickly under thumb pressure (0.5 minutes at 30°C/86°F, 1 minute at 20°C/68°F, 10 minutes at 5°C/41°F).
