Protecting Dacron Ultra-Light 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 coloured PolyTone or Areo-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 60×48-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.
Coverage: one gallon catalyzed Aero-Thane AO-100 enamel will cover approximately 225 sq ft with one coat.
Clean Up: 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.
