ZC-1251
Both ZC-1251 and ZC-1392 are designed to remain undarkened by particle radiation from the solar wind (such as that found in geostationary orbit) and to remain undamaged by atomic oxygen (found in low Earth orbit). ZC-1251 is optimized for the highest infrared reflectance (low thermal emissivity).
