AZO-5000-PF Fluoropolymer Transparent Paint/Coating

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.
