2. About Spray Painting
 Spray painting existed since 1800’s. It was developed to consume time
process when compared to brush painting.
 Spray painting is the easiest method to paint in a shorter period of time
using spray gun.
 The right method to follow is the paint is mixed together with a water or
solvent.
 Depending on the requirements, the booth is filled with filtered air to
avoid the dust particles and exhaust air system to clear the fumes of
evaporating solvents that is used in the paint spraying process.

3. Humidity and Temperature
Control System
The best conditions to follow while paint inside paint booths
are 65 to 75%rh and 20 to 24°C.

4. “
If in order to reach desired values then either you have
to dry or humidify the air.
In temperature section the air might need to be heated
or cooled depends on outside temperature.

5. Humidity Control
System
For a spray painting chamber where the air being
forced via a duct to spray painting is totally
humidified by the combination of water from
pressurized water and air sources respectively.
Humidity control system comprises of,

6. Nozzle
For atomizing the water, mixing water and air
directly supply the air into the duct to form
humidified air, so that it have relative humidity
level

7. Valve
For limiting the flow of water from
pressurized water source

8. Motor
Opening and closing the valve at
predetermined rate

9. “
Based on this method the valve is opened or closed is not less
than 1 hour between completely closed or opened positions.
Then the motor has an output shaft that rotates not more than
one revolution per minute.
The water is atomized to produce water particles less than 200
microns.

10. Paint booth should be a minimum of 55° for all automotive
paint. But all automotive paint companies takes time to
recoat, cure and flash etc.
on 70° and 50% relative humidity. Basic rule have to follow
is for every 15° above 70° the coating cures fast.
If this rule is below 70° the coating will take twice as long to
cure, simply it’s vice versa.
Auto Refinish
Situation

11. The above information is true when it is up to 55° because
the catalyst becomes quiescent and it doesn’t crosslink.
Since most of the countries are much warmer than 70° at-
least few years.
Basically, paint companies have variety of reducer and
catalyst to compensate for rapid increase in the cure when
applying coatings.
Facts

12. Why Temperature
Control Is Important?
Spraying the products takes 30 minutes at
70° to flash before coated with next step; a
shop can reduce the time about just 15
minutes provided if the shop has the ability to
increase the temperature to 85°.

13. Temperature
Settings In Industrial
Applications
Right temperature for each paint job will be a more
intricate process.
Average temperature cures paint between 65° and
70° F. You have to carefully look these points
 What type of coating you are using? Type differs
from one paint manufacturer to another
 Next, what you are painting? Size of the object
will affect long duration it takes to dry and setting
up the suitable temperature to dry
