First Aid

If molten hot melt comes in contact with your skin:

1. Do NOT attempt to remove the molten hot melt from your skin.

2. Immediately soak the affected area in clean, cold water until the hot melt has cooled.

3. Do NOT attempt to remove the solidified hot melt from your skin.

4. In case of severe burns, treat for shock.

5. Seek expert medical attention immediately. Give the MSDS for the hot melt to the

medical personnel providing treatment.

Description

See Figure 1. The Nordson AG-900+/AG900+S modular dispensing applicator is a

noncirculating unit that applies solid and foamed high performance materials such as

silicones, plastisols, urethanes, epoxies, butyls and hot melts. The applicator is compatible

with a variety of Nordson systems and is well suited for automated dispensing equipment.

8. Needle/nozzle assembly

The applicator is pneumatically triggered by a customer supplied external solenoid. The

applicator assembly includes a module, and either a pressure regulator (heated or

unheated) or applicator adapter body.

The AG-900+/AG900+S dispensing applicator is available as a zero cavity needle/nozzle

design, or can be provided to accept standard extrusion nozzles.

Heated AG-900+/AG900+S applicators have replaceable heater cartridge(s) in the heater

block assembly mounted to the module. Resistance temperature detectors (RTDs) in the

hose and in the heater block monitor temperature. Cordsets from the hose and from the

heater block are connected electrically to a controlled power source such as a FoamMix

processor or a standalone temperature controller.

AG900+/AG900+S applicators are set up from the factory to operate as

air-open-spring-close actuation for use in dispensing lower viscosity materials. Air-close

operation can be used when using materials of higher viscosity.

NOTE: If the air−close will be used, order part number 1096469 solenoid assembly

with tubing.

Needle and Nozzle Design

AG-900+/AG900+S applicators accommodate needle and nozzle designs selected for each

application requirement. The zero cavity needle/nozzle applicator describes zero space

downstream to the cut-off where the nozzle and needle join. This prevents material from

leaking, clogging and backing up in the applicator-on positions.

Material Pressure Regulator

AG-900+/AG900+S applicators are available with an optional material pressure regulator

attached directly to the applicator module. This regulator provides consistent material

pressure to maintain constant output rates.
