APPLICATION:
KEYSITE 740 may be applied by airless or conventional spray. Use "cross
spray" application procedure. Move gun fast enough to avoid runs or sags.
When KEYSITE 740 is applied at 160 square feet per gallon, wet film thickness
should be 8 mils to obtain 6 mils dry film thickness. Allow for loss due to
application methods and conditions of surface irregularities. KEYSITE 740 can
also be applied by brush.
SPRAY EQUIPMENT:
Conventional Spray -
DeVilbis JGA gun with "E" tip and needle, #765 air cap on 1/4"
air hose, 3/8" material hose and standard pressure pot. Airless Spray -
GRACO 6-21, Orifice top - 1/4" I.D., teflon material hose and 30.1 ratio
pump.
CLEAN UP: Clean
spray equipment thoroughly with KEYSITE 740 thinner.
SHIPPING WEIGHTS: Packaging
and Shipping Weight: 1 Gallon Kit 13 lbs, 5 Gallon Kit 55 lbs.
SAFETY AND SHIPPING INFORMATION:
Precautions - Keep away from heat, sparks and open flame. Use of fresh air
supplied mask during application is recommended. Avoid prolonged contact with
skin and breathing of vapor or spray mist. Adequate ventilation is required.

KEYSITE 740
GENERAL APPLICATION SPECIFICATION
SPRAY
1. Combine Part B with Part A of one kit, stir thoroughly.
Spray all material out of pot before combining a new kit. Catalyzed material
must be removed from pot and material hose at lunch break and at end of every
application period. If temperature is 100 degrees. F., or over, add not OVER
1/2 pint pr gal. of Keysite 700 thinner to prevent jelling in spray pot during
application.
2. Use only clean, dry air at 30 to 40 lbs. pot pressure
and 40 to 50 psi atomization (material pressure) in standard production type
spray equipment - such as DeVilbis MBC or JGA gun with "D" tip and
needle and #24 air cap on 1/4" air hose and 3/8" material hose and
standard pressure pot.
3. Use "cross spray" application procedure. Move
gun fast enough to avoid runs or sags. Wet film thickness per coat should b 6
to 8 mils. Allow each coat to air dry tack free. This will require only 16 to
24 hours @ 790°F. in properly ventilated area.
4. Clean spray equipment thoroughly with Keysite thinner
after use.
B. BRUSH
1. Use a pure bristle only. Do not use Nylon.
2. Normally , apply Keysite 740 as is direct from can after
mixing. For additional flow in cold weather, thin with 5% Keysite thinner
only.
3. Allow each coat to air dry - same as in spray
application.
4. Recommended coating thickness:
Class 1 - (12 to 15 mil Holiday Free Dry Film thickness)
Immersion
Strong Fumes
Strong corrosive splash or spillage
mild abrasion ( may be reinforced with glass cloth - (see
application instructions)
Class 2 - (8 to 10 mil Holiday free dry film thickness)
Mild splash
Normal fumes

type gage (Elcometer or equal).
5.5 coating shall extend through all flange necks and across full
flange face.
