MIXING INSTRUCTIONS

Shake component A in a paint shaker for 5 – 10 minutes for optimal results.Admix by volume:

• 2 Part Component A (Base)
• 1 Part Component B (Catalyst)
• Add the Catalyst into the Base.

APPLICATION

This product can be applied by brushing, rolling or using conventional air spray equipment, HVLP spray system. Please consult with a PTI representative for specific equipment recommendations and settings.

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: fullest coverage apply 3 coats: 1 fog/tack coat & 2 full coats 0.6 – 1 mil thickness.
6. Do not allow more than 48 hours to pass before applying the second coat.
7. Recommended Dry Film Thickness is 1-2 mils. Some colors may require thicker films to achieve hiding.
8. For wet sanding or buffing of coating, wait a minimum of 13 hours but not more than 26 hours. NOTE: If paint is allowed to cure for more than 48 hours wet sanding and buffing is not possible.

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.
