* Actual specification values will vary depending on adhesive type and application parameters. 1
PH values outside the recommended range may result in corrosion or damage of seals, either of which will reduce the life and performance of the applicator. In case of unexpected corrosion due to adhesive used, the glue supplier needs to be contacted to identify an inhibitor that can be used as an additive to the glue to minimize corrosive effects.
2
Actual cycle time will vary depending on adhesive viscosity and characteristic. The minimum “on time” is defined by the bead length, the minimum “off time” is defined by the gap between two beads.
Note: Adhesive used needs to be solvent-free Note: 1 bar = 14.5 psi = 105Pa Note: 0.4536 kg = 1 lb Note: 9 x °C/5 +32 = °F Note: 25.4 mm = 1 in. Note: 1 cps = 1 cP = 1 mPa s = 1 mNs/m2
