When using a suction-feed type spray gun, the ears of the air cap should be set:
:perpendicular to the direction of the spray gun movement across the surface being sprayed.
:at a 45 degree angle to the direction of the spray gun movement across the surface being sprayed.
:parallel to the direction of the spray gun movement across the surface being sprayed. - ANS_parallel to
the direction of the spray gun movement across the surface being sprayed.
Which defect in aircraft finishes may be caused by adverse humidity, drafts, or sudden changes in
temperature?
:Pinholes.
:Orange peel.
:Blushing. - ANS_Blushing.
What is used to measure the viscosity of a painting material to determine if it has been properly
thinned?
:Seyboth tester.
:Wet film paint gauge.
:Viscosity cup - ANS_Viscosity cup
What is likely to occur if hydrated wash primer is applied to unpainted aluminum and then about 30 to
40 minutes later a finish topcoat, when the humidity is low
:a glossy blue free finish
:a dull finish due to the topcoat sinking in to primer that is still too soft
, :corrosion - ANS_a glossy blue free finish
Fungicidal dopes are used in aircraft finishing as the
:final, full bodied brushed on coat to reduce blushing
:first coat to prevent fabric rotting and are applied thin enough to saturate the fabric
:first, full bodied, brushed on coat to prevent fungus damage - ANS_first coat to prevent fabric rotting
and are applied thin enough to saturate the fabric
Aluminum pigment in dope is used primarily to
:aid in sealing out moisture from the fabric
:reflect ultraviolet from the fabric
:provide a silver color - ANS_reflect ultraviolet from the fabric
What is used to slow the drying time of some finishes and to prevent blush
:retarder
:rejuvenator
:reducer - ANS_retarder
A correct use for acetone is to
:thin dope
:remove grease from fabric
:thin zinc chromate primer - ANS_remove grease from fabric
Which statement is true regarding paint systems compatibility
:old wash primer coats may be overcoated directly with epoxy finishes
:acrylic nitrocellulose lacquers may be used over old nitrocellulose finishes
