Usage instructions
2.2 Field of application
The solvent-free cyanoacrylate group-based superglue CA80 is intended for the
installation of strain gages (SG). It is suitable for SG in the series:
Y, C, LD, E and residual stress SG (optimal suitability)
G (good suitability)
CA80 is not suitable for bonding porous materials, such as wood, concrete or foam. The
customer must qualify and assess the quality of the adhesive bond.
With cyanoacrylate adhesives, curing is initiated by the catalytic effect of the humidity
absorbed from the air. Relative humidity between 40% and 70% provides the best
conditions. If the relative humidity is less than 30%, the reaction is noticeably delayed and
in extreme cases, may not occur at all. If the relative humidity is greater than 80%,
impact
curing will result. CA80 will only cure in thin layers in the given time. Thick layers of
adhesive will not cure completely or even at all. Heavily scratched or rough surfaces are
therefore unsuitable.
The curing rate depends on the chemical state of the components to be bonded. Basic
surfaces
speed up the hardening process, acidic surfaces can not only delay curing, they
may also prevent it. In this case, use the accelerator BCY01, which is available separately.
Table
Tab. 2.1 shows the recommended values for the hardening time, subject to the
material to be bonded, at a temperature of 20
°
C and a relative humidity of 65%.
