SPECIAL RECOMMENDATIONS
· This paint is a low-outgassing version of PSG 120 from the same manufacturer, which was used on several space projects. · Whereas the PSG120 version requires a high-temperature cure, PSG120FD can be cured at room temperature. · On high-absorbtance substrates the paint layer must be at least 200mm thick if low final absorbtance is required. · Must be used with primer P128 from Astral. · See ECSS-Q-70-33 for application process. · Equivalent MAP product: SG120FD.
