LOCTITE® Product 493 is a very low viscosity methyl
cyanoacrylate adhesive.
TYPICAL APPLICATIONS

Shelf life at 20âC, months 12
FIXTURING TIME
This is defined as the number of seconds after assembly when
a joint develops a tensile shear strength of 0.1 N/mm2
measured at 22âC, 50% relative humidity according to ASTM
D1002 and DIN 53283. This cure speed is affected by the
nature of the substrate, ambient humidity and temperature.
High cure speed is favoured by thin bond lines and by avoiding
excess adhesive.
Performance of Loctite Product 493 on metallic and nonmetallic
substrates:
Substrate Fixture Time, seconds
Mild steel (degreased) 20 to 40
Aluminium (degreased) 30 to 60
Zinc bichromate 30 to 60
Neoprene rubber < 10
Nitrile rubber < 10
ABS 10 to 30
PVC 30 to 70
Polycarbonate 20 to 70
Phenolic materials 10 to 30
Where cure speed is inadequate, due to low relative humidity,
or large gaps, a LOCTITE ACTIVATOR may be used. This
can, however, lead to a reduction in eventual strength of the
bond and careful testing is recommended before use in
production.
While full functional strength is developed in a relatively short
time, curing continues for at least 24 hours before full chemical
and solvent resistance is developed.
