6 Application Hints
The Loctite ® EQ VA40 is specifically designed to dispense drops of Loctite®
Cyanoacrylate Adhesive. This adhesive is moisture sensitive. Clean dry air must be
used to pressurize adhesive but for best results dry nitrogen is recommended.
Shutdown – Always keep the Loctite® EQ VA40 CA Volumetric Valve full of adhesive.
At the end of the day depressurize the reservoir. The dispense needle will cure and seal
the system. Always install a new dispense tip after all extended shutdown periods.
