AZ Technology’s fluoropolymer transparent protective paint is a solution based material developed for use on ceramic thermal control spacecraft / satellite paints / coatings. The applied coating provides contamination protection for sensitive ceramic thermal control coatings during assembly and integration. This material is a sacrificial coating that erodes away when exposed to atomic oxygen in low earth orbit leaving the coating being protected in pristine condition. AZO-5000-PF protective coating when used in conjunction with ceramic thermal control coatings, including AZ-93, provides excellent protection against handling and other common ground sources of contamination; including particles and fluids.
The table below lists the optical and application parameters of cured AZO-5000-PF.

|Nominal Dry Thickness||0.25 ± 0.5 mils (over 85% of coated area)|
|Thermal Emittance (ε_t)||≤0.05 Decrease|
|Solar Absorptance (α_s)||≤ 1% Increase|
|Full Cure||24 to 48 hours|
|Coating coverage estimates can be found here.|
Note: terms reflectance, emittance and absorptance and terms reflectivity, emissivity and absorptivity are often used interchangeably.
