Know Your Coatings; Coating Properties; Your Choice Of Coatings And Viscosity - Apollo Sprayers PRECISION-6 Instruction Manual

Normal triggering of the spray gun during a pass will prevent the turbo system from entering "IDLE MODE". *All turbine
pressures quoted are measured sealed and at the motor outlet. Actual spraying pressures will vary depending on the model
and size of the turbine.

4 Know Your Coatings

4.1 Coating Properties

Coatings are a blend of resins and additives to create a product that will provide a protective and beautifying surface to your
work piece. Different resins have different properties. It is important to use the correct coating to achieve a desired result.
Manufacturers of coatings can control the resin solids content, production viscosity, sheen, color, flow-out enhancement and
other properties. Some products offer ways to adjust the coating properties such as speeding up or slowing down the drying
time, adding catalysts to strengthen the molecular bond or adding flatting agents to lower the sheen. Manufacturers will often
give some guidelines on how to thin their product for spray application. There are many different types of spray equipment in
use. Coatings manufacturers cannot address all of them. It is important for the finisher to understand the spray equipment
and to use common sense to arrive at the correct fluid viscosity to produce the best possible results with the selected coating
and the equipment being used.

4.2 Your Choice of Coatings and Viscosity

Extremely thin, watery or light bodied fluids such as inks, aniline dyes and oil stains can generally be used straight from t he
can. RTS or Ready to Spray water based finishing products are formulated to be used straight from the can without thinning
with a 3 stage or larger turbine. Most other coating products should be thinned according to the manufacturers guidelines Chart
"A" below shows you the approximate air pressure needed to spray a given viscosity range.

Using Latex (Emulsion) Paint
Although your turbine spray system is best suited to spray Class A Finish coatings such as lacquers, enamels, urethanes,
varnishes, waterborne and water base etc., you can spray latex (emulsion) house paint if you follow a few simple rules. First , it
is generally necessary to thin latex (emulsion) paint. This will vary from as little as 10% to as much as 50% depending on the
air pressure you choose and the quality of the paint used. Second, it is necessary to use a larger nozzle and needle set in the
spray gun (1.8mm or 2.0mm) when spraying doors or larger areas. If you are spraying latex on cabinets or fine woodworking you
should use a smaller needle and nozzle in order to decrease the droplet size. We recommend that you use a 1.5mm nozzle with
the C-HS air cap for this application type. It is recommended that a latex (emulsion) paint conditioner like Floetrol®, be added
to aid flow-out. These products are sold at local paint stores. Some brands of paints have their own flow additive, if this is the
case with the latex paint you choose always use the recommended flow additive.
