PPG announced that it provided aerospace sealants, coatings and adhesives to United Launch Alliance (ULA) for the ATLAS V 541 rocket that launched NASA’s Perseverance rover to Mars in July 2020. The rover landed on the Red Planet in February 2021 after its nearly seven-month journey through space.
PPG’s application support center (ASC) in Atlanta, Georgia, worked closely with ULA to supply the products and provide technical support. With more than a century of combined heritage, ULA is the worlds most experienced and reliable launch service provider. ULA has successfully launched more than 140 missions to orbit that provide Earth observation capabilities, enable global communications, unlock the mysteries of our solar system and support life-saving technology.
PPG products protecting the rocket include PPG DESOTHANE™ CA8200 Series HS polyurethane topcoat; PPG PR-2001 Class B rapid-curing fuel tank sealant, which is a two-part, epoxy-cured PERMAPOL™ P-3.1 polythioether compound; and PPG PR-1665, which is a cryogenic potting and molding compound with high tear and tensile strength.
