PPG is launching its new Pro-Seal 815M aerospace sealant spray next month. According to the company, the new sealant spray has the potential to reduce aircraft assembly times by curing the surface of the sealant to a tack-free state in two to three hours compared to the time required for untreated sealants to reach the same condition, which can range from six to more than 40 hours.
“I have never met a customer who was not actively looking for ways to speed up the sealing process of an aircraft, while also expecting the applied sealant to look perfect,” says Bill Keller, PPG’s global market segment manager, aerospace sealants. “The artisans who apply aerospace sealants commonly spend vast amounts of time tooling the sealant to meet dimensional and appearance specifications. To accelerate this process, they often use unapproved solvents that could be detrimental to the sealant’s performance and longevity.”
According to Keller, Pro-Seal 815M is both quicker and easier to use than other comparable products. The clear spray, which can be used throughout the aircraft anywhere polysulfide aerospace sealants are applied, comes ready to use in a non-aerosol recyclable pump bottle. Once sprayed on wet sealant, Pro-Seal 815M helps break the surface tension and cures the sealant at 25C (77F), which allows for easier smoothing and fairing to meet dimensional requirements and optimal appearance.
PPG says the idea for the product was first developed approximately four years ago and the company leveraged its expertise in aerospace sealant technology and application to accelerate its development. Before the March launch of the product, PPG will be offering advance samples of Pro-Seal 815M. Samples will be available by request and at the 2018 Singapore Airshow this week.
