Reportedly, applications for chrome-free corrosion-inhibiting aerospace sealants continues to grow as aircraft manufacturers and maintenance, repair and overhaul shops report the product surpasses their process and performance expectations. Available in all three classes, PRC® PR-2870 sealant is stated to be becoming the new standard by which other corrosion-inhibiting sealants are measured.
“It is the right stuff at the right time,” said Bill Keller, PPG global market segment manager for aerospace sealants. “When we asked customers to name the properties they wanted in their sealants, first was rapid cure, and light weight was a close second. All PR-2870 sealant classes cure faster than our previous-generation corrosion-inhibiting sealant, while Classes A and B weigh as much as 30 percent less by volume.”
