Aero-Thane 100 Clear
A tough, flexible, two-part clear polyurethane recommended to retain the original brilliance of polished aluminum. Not recommended when the aircraft will be exposed to severe environmental pollution.
PROTECTING DACRON ULTRALIGHT SAILS: Clear Aero-Thane is used to seal and provide UV protection for Stabilized Dacron or nylon ultralight fabric. Mix and thin Aero-Thane as instructed below and spray two or three coats over clean sails to provide UV protection. Clear Aero-Thane has UV blockers that protect sails and markedly extend their service life. Clear Aero-Thane will not change the appearance of the fabric or increase its gloss.
CAUTION: Clear Aero-Thane should not be applied over colored PolyTone or Aero-Thane to increase the gloss of those paints. Clear Aero-Thane is only to be used on ultralight sails; it is not suitable as a generic clear coat.
MIXING PROCEDURE: Add 1 part U-865 catalyst to 3 parts Aero-Thane base (1 qt to 3/4 gal). Stir thoroughly. Ratio must be accurate for best characteristics. Allow 20 minutes induction time before thinning.
THINNING: For standard suction guns (compressors), thin Aero-Thane 33%. An easy measurement is 3 parts catalyzed Aero-Thane to 1 part UE-820 Reducer. For turbine-powered HVLPs, you may need to thin more, up to 40% (3:2 ratio). Filter through a 60x48-mesh or finer paint strainer cone.
APPLICATION PROCEDURE: Spray for best results. Clear Aero-Thane was meant to be sprayed; brushing or rolling may result in a rough finish. Spray when temperature is above 55°F.
One gallon catalyzed Aero-Thane AO-100 enamel will cover approximately 225 sq ft with one coat.
The sooner Aero-Thane is applied after the induction period the better the durability. Maximum pot life is seven hours at 77°F. Discard materials when viscosity increases or becomes stringy when tested between the fingers. Do not add reducer to extend pot life after thickening occurs.
EXTENDED POT LIFE:
The polymerization of the catalyzed paint may be suspended 24 hours or longer by storing at 30°F. or less in a refrigerator. Warm to room temperature before spraying.
Use MEK or UE-820 Reducer before material has started to polymerize in the equipment.
DRY DUST FREE:
One hour at 77°F. and approximately 50% relative humidity.
DRY TO TAPE:
10 to 12 hours at 77°F. and approximately 50% relative humidity.
FULL CURE TIME:
Seven days at 77°F. and approximately 50% relative humidity.
All surfaces which have cured more than two days should be scuff sanded to provide tooth adhesion for the new coat. Use Scotch-Brite No. 7448 pads or 400-grit wet-or-dry sandpaper. May be removed from metal surfaces with any commercial paint stripper.
Areas to be refinished after repairs should be masked to a structural division line or seam or the overspray levelled with a "melt-in" by immediately mist coating the area with a mixture of 1 qt. UE-820 Reducer to 1 oz UR-826 Retarder.
Guaranteed shelf life, unopened, in protected storage at room temperature is four years from date of manufacture. Avoid long-range storage above 100°F. Not affected by freezing.
One-quart and one-gallon kits only.
One-Quart Kit = 3/4-filled quart base component plus 1/2 pint of catalyst.
One-Gallon Kit = 3/4-filled gallon base component plus 1 quart of catalyst.
