The products developed by PPG were used to protect the ATLAS V 541 rocket that launched NASA’s Perseverance rover to the Red Planet.
PPG has announced that its aerospace sealants, coatings and adhesive products were provided to United Launch Alliance (ULA) for the rocket ATLAS V 541 that, in July 2020, launched NASA’s rover Perseverance to Mars. After almost seven moths travelling through space, Perseverance landed on Mars in February 2021.
"Our aerospace sealants, coatings and adhesives helped ULA provide protection for the Atlas V 541 rocket, which aided the Perseverance rover in reaching its final destination. We are proud to support this important and historic mission and look forward to a continued partnership with ULA for years to come," said Sam Millikin, PPG global director, coatings and sealants, aerospace.
ATLAS V 541 is one of the best rockets among ULA’s fleet, thanks to its four solid rocket boosters that provide optimal performance in order to deliver several ranges of mission. The PPG application support centre in Atlanta (Georgia, USA) cooperated closely with ULA and provided technical support and products such as the polyurethane topcoat PPG DESOTHANE™ CA8200 Series HS, the rapid-curing fuel tank sealant PPG PR-2001 Class B – a two-part, epoxy-cured PERMAPOL™ P-3.1 polythioether compound – and PPG PR-1665, a cryogenic potting and moulding compound that possesses high tear and tensile strength.
