SETUP + USE

Spray Gun Controls + Inputs

A. Pattern Width Control

This knob controls how Simalfa will come out of the gun. As the knob is

threaded into the gun (tightened), the fan pattern will narrow. As the

knob is unthreaded (loosened), the fan pattern will become wider. It is

important to note that as the fan pattern becomes wider, the air pressure

must also increase to accommodate this.

B. Fluid Knob

This knob controls how much glue will come out of the gun with a full trigger squeeze. As the

knob is threaded into the gun (tightened), the maximum adhesive amount is reduced. As the knob is

unthreaded (loosened), the maximum adhesive amount is increased. A simple rule: less threads = less adhesive,

more threads = more adhesive.

C. Atomization Air Regulator

This is where the atomization air pressure can be adjusted. Turning clockwise decreases atomization air while

turning counter clockwise increases atomization air. However, it is recommended that a wall regulator be installed

for each spray gun to limit the maximum air pressure at the spray gun. Most shop air pressure can be 100+ psi and

that is too high for proper use of an HVLP spray gun.

D. Atomization Air Input

This is where the atomization airline is attached. We suggest using both the atomization air regulator contained

within the Simalfa spray gun and a wall regulator to insure proper atomization. Learn about setting the proper

atomization air in the next section titled “Setting Atomization Air Pressure”.

E. Trigger

Controls the amount of adhesive exiting the spray gun. It’s similar to a gas pedal on a car, the further you pull the

trigger the more adhesive exiting the spray gun.

F. Adhesive Input

This is where the uid hose is attached. 1/2” PVC Fluid Hose and Stainless Steel connectors required.

G. Adhesive Exit Point

This is where the adhesive will exit the spray gun. At this point, all settings such as adhesive volume, pattern width,

atomization pressures come together for application.

Setting Atomization Air Pressure

The key in setting air pressure is understanding that the uid

volume and pattern width a user desires will determine the

PSI required for atomization. That being said, it is impossible

to give an exact setting for all users since each has their own

needs and objectives.

On average, our customers have atomization air pressures set

in the range of (25psi-50psi / about 1.7 - 3.5 Bar). Factors

such as a user’s process, substrates and application will dictate

the required uid volume and pattern width and subsequently

the correct air pressure needed. For example an application

requiring a very small amount of adhesive sprayed in a very

narrow pattern will require low air pressure. There are some

users spraying in the area of 20psi (about 1.4 bar). However,

we also have users where there’s a need for greater uid

volume sprayed in a wide pattern and the air pressure is set at

over 60psi (about 4.13 bar).

Adjust the air pressure to where the adhesive appears in very

ne droplets. The diagrams on the right illustrate CORRECT

and INCORRECT atomization air pressures as it relates to uid

volume and pattern width.

A. Correct Atomization Air Pressure.

Atomization air is set correctly for the uid volume and

pattern. Simalfa appears in ne droplets to maximize the

efciency and performance.

B. Incorrect Atomization Air Pressure.

Droplets too coarse for the pattern width and uid volume.

Simalfa will not perform as designed.

SOLUTION: Increase air pressure so droplets appear ne, and/

or decrease pattern width, and/or decrease uid volume so

adhesive appears in ne droplets as in diagram A.

SETUP + USE

Recommended Spray Techniques

Distance from Substrate.

When applying Simalfa the spray gun should be held at a

distance between 6”-10” (15cm - 25cm) from the substrate.

Pattern Width.

Keep it narrow. A narrow spray pattern gives greater control

over where the adhesive is applied. Wide spray patterns create

waste, mess and overspray.

Angle to Substrate.

Spray Simalfa directly at the substrate, not across or on an

angle. This will insure the most economical application and

reduce any potential for overspray.

Method.

The user should have a sweeping motion left to right and

right to left. A single pass of a light even coverage should be

sufcient. A short pulsating technique will waste adhesive and

cause inconsistencies in the nal bond.

Application.

Application amount is determined by the handling strength

required during the production process and/or the complexity

of the application itself. Simalfa can be sprayed lighter on

easier applications or heavier on more difcult applications. It

is important not to over-apply Simalfa as this creates waste.

SETUP + USE

CLEANING +MAINTAINING

WARNING: Prior to any servicing and repair work the spray gun must

be removed from atomizing air pressure and material inputs.

Procedures to always follow:

1. Always swap spray gun at spray station.

2. Always service spray gun immediately. The swapping and/or maintenance of a spray gun should

take about 5 minutes. If maintenance is not immediate and adhesive is allowed to dry, expect

servicing time of about 1 hour, not including the possible interruption in production if gun is not

prepared in a timely fashion.

Things to avoid:

1. Never maintain spray guns while attached to uid line. This will allow adhesive to ow into

the air passageways of the spray gun body causing the compressed air to cure the adhesive,

increasing the maintenance time drastically.

2. Never use any petroleum-based product (i.e. solvent, petroleum jelly, etc.) to clean or lubricate

areas of spray gun where uid may contact.

3. Never submerge spray gun in solvents or other cleaning uids, as this will impair the functional

reliability and efciency of the gun. This will cause more service over time.

Servicing procedures:

1. Remove spray gun from spray system and replace with serviced spray gun.

2. Flush excess adhesive from spray gun using water.

3. Remove air cap, uid nozzle and needle.

4. Flush gun body with water until thoroughly clean. Make sure adhesive does not get inside air

passageways.

5. Clean all parts and remove any dried adhesive on these components and again ush thoroughly.

6. Assemble spray gun. Always install uid nozzle before uid needle. (If parts need replacement,

do it now. We only want fully serviced and repaired guns to be placed into production.)

7. Test for leaks using water. Turn spray gun upside down and ll with water. Check to see if

leaking at nozzle uid nozzle. If leaking replaced both nozzle and needle. (Much easier when

done with water vs. after attaching to adhesive system)

8. Place in a convenient location for next use.

CONFIGURACI

N + USO

Controles de la pistola + Entradas

A. Control del abanico

Esta perilla controla como va a salir el adhesivo Simalfa de la pistola.

A medida que la perilla es enroscada en la pistola (Apretada) el abanico

será más estrecho. A medida que la perilla es desenroscada, el abanico

será más amplio.

Es importante notar que a medida que el patrón del abanico aumenta, la

presión de aire tendrá que ser incrementada.

B. Perilla de Fluido

Esta perilla controla la cantidad de adhesivo que saldrá de la pistola cuando el gatillo se aprieta totalmente. A

medida que la perilla es enroscada en la pistola (Apretada) la cantidad máxima de adhesivo es reducida. A medida

que la perilla es desenroscada, la cantidad máxima de adhesivo será aumentada.

Regla: menos rosca = menos adhesivo, mas rosca = mas adhesivo

C. Regulador presión de aire

Esta perilla es donde se ajusta la atomización del aire en la pistola. Girar la perilla en el sentido de las manecillas

del reloj disminuye la atomización de aire; girar en el sentido contrario a las manecillas del reloj aumentara la

atomización del aire. De cualquier forma se recomienda instalar un regulador de aire para cada pistola para que se

pueda limitar la presión de aire de entrada ya que la mayoría de instalaciones superan los 100 psi.

D. Entrada de aire

Acá es donde se conecta la línea del aire. Sugerimos que se utilicen tanto el regulador de aire de la pistola como el

convencional para asegurar una atomización correcta.

Aprenda mas sobre la forma correcta de atomización en la sección “Ajustando la atomización del aire”

E. Gatillo

Contrala la cantidad de adhesivo que sale de la pistola. Es similar al acelerador de un carro; a medida que se jala el

gatillo aumenta la cantidad de adhesivo que saldrá de la pistola.

F. Entrada de adhesivo

Acá es donde la manguera de adhesivo va conectada. Manguera de ½” y conectores necesarios.

G. Punto de salida de adhesivo

Acá es donde el adhesivo sale de la pistola. Las conguraciones tales como Volumen de adhesivo, abanico, presión

de aire se juntan para dar paso a la aplicación.
