LA 725 and LA 725-S
Liquid Adhesive Dispensing Applicators
Benefits
n
Extended operating life, two to three times longer, due to the patented,
frictionless silicone seal
n
Faster cycle times using new, high-speed solenoid technology, particularly
beneficial for stitching and dotting patterns
n
Less downtime and maintenance due to the robust design and construction
n
Quick change module, solenoid or cartridge
n
Sharp, clean cutoff from snuff-back technology
Nordson LA 725 and LA 725-S pneumatic applicators deliver production
efficiency and clean, repeatable liquid adhesive patterns. LA 725 applicators have
a long service life and perform consistently in even high-speed production. These
applicators support both continuous and intermittent operation and are ideal for
non-contact and contact bead applications, as well as slot applications, for a wide
production range including folding carton, bag & sack and packaging.
The patented LA 725 and LA 725-S applicators use an advanced hydraulic seal
technology resistant to most chemicals used in water-based adhesives so it lasts
longer and requires less maintenance than typical seals. And, the frictionless
operation extends service life even more.
The fast-cycling guns and snuff-back technology support sharp, clean cutoff
on even high-speed production lines. Resulting patterns are reliably uniform
in appearance and performance, allowing you to optimize adhesive use and
reduce waste.
LA 725 applicators install easily into most parent machines and quick change
components minimize downtime and facilitate quick production changeovers.
Fast-cycling pneumatic applicators
deliver precise, repeatable bead
or slot adhesive patterns in
continuous or intermittent production.

* Actual specification values will vary depending on adhesive type
and application parameters.
1
Cycle time will vary depending on adhesive pressure, viscosity and
other characteristics.
2
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.
Note: Adhesive used needs to be solvent-free
