SHELF LIFE

Shelf life is only applicable for materials stored in unopened and undamaged original factory filled containers.1 year when stored at 50⁰-85⁰ F.Shake component A in a paint shaker for 5 – 10 minutes for optimal results.

Admix by volume:

For a Viscosity of 22 seconds in a #2 Zahn:

• 4 Parts Component A (Base)
• 1 Part Component B (Catalyst)
• 1 Part Distilled Water (Reducer)

For a Viscosity of 18 seconds in a #2 Zahn:

• 4 Parts Component A (Base)
• 1 Part Component B (Catalyst)
• 2 Parts Distilled Water (Reducer)

Add the Catalyst into the Base.

Admixed material should be allowed a 45-minute induction time for best application results.
Reduce: Use distilled water to thin or reduce the primer according to the instructions above. DO NOT OVER-THIN THIS MATERIAL.

APPLICATION

This product can be applied by brushing, rolling or using conventional air or HVLP spray equipment.

1. Make sure pots, guns, and lines are purged and cleaned.
2. Mix both base and catalyst thoroughly and filter/strain before spray application.NOTE: It is not recommended to strain flat/matte coatings.
3. HVLP spray pressure: 7-10psi. Conventional spray pressure 15-30psi
4. Always air-blow and tack wipe the surfaces to be painted. Aircraft should be grounded to prevent static.
5. Best application results: apply 2 coats: 1 fog/tack coat & 1 full coats from 0.6 – 0.9 mil thickness.
6. Do not allow more than 24 hours to pass before applying the second coat.
7. Recommended Dry Film Thickness is 0.6-0.9 mils. Some colors may require thicker films to achieve hiding.

NOTE: Application of PTI products requires the use of all OSHA approved safety equipment, including proper ventilation. Additionally, PTI products require the recommended temperature/humidity conditions and film thickness ranges for optimal performance. The material, hangar, and aircraft skin temperatures should be no lower than 75⁰ F / 25⁰ C before, during and after application.

DRYING & CURING SCHEDULE

Dry times are based on the dry film thickness between 0.6 - 0.9 mils (25-50 microns).Air Cure:Tack Free 60 minutes maximumDry Hard 6 hours maximumForce Cure:Tack Free ½ hour @150FDry Hard 1 hour @ 150F Always bring the coating to the “tack free” stage before top coating.

If using PTI additives to adjust the dry and cure times of the coating, please refer to those Product DataSheets for specific instructions for admixing the material.
