Adhesives, sealants and coatings manufacturer PPG provided aerospace sealants, coatings, and adhesives to United Launch Alliance (ULA) for the ATLAS V 541 rocket that proved critical to the launch of NASA’s Perseverance rover to Mars. The rover landed on Mars in February 2021 after its nearly seven-month journey through space.

As one of the most powerful rockets in ULA’s Atlas V fleet, the 541 configuration with four solid rocket boosters reportedly provides optimum performance to precisely deliver a range of mission types. 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, according to the company.
