New Prestone® Triple Seal Protection™ Stop Leak Made with DuPont™ Kevlar® Resin Helps Avoid Costly Engine Repairs

July 17th, 2015

After years of development, Prestone unveils the latest in car care technology  

LAKE FOREST, IL – July 17, 2015 – Prestone, the innovation leader in cooling system products, has released the newest breakthrough to help cars run better and consumers avoid expensive engine repairs. Utilizing an advanced proprietary patent-pending formula, Prestone's line of Triple Seal Protection Stop Leak products enable do-it-yourselfers to stop cooling system leaks without an expensive trip to the mechanic.

The three revolutionary new items, Prestone's Triple Seal Protection Engine Block Stop Leak, Head Gasket Stop Leak, and Radiator Stop Leak each come with Prestone's unique Triple Seal Protection, a reasonably priced and high-quality solution to protect today's sophisticated engines. The Triple Seal Protection formula contains effervescent beads that go straight to the source of the leak, Kevlar® resin then forms a web that binds to the metal, while an acrylic polymer hardens and secures the seal. Best of all, the Triple Seal Protection system stops leaks fast without blocking or corroding the cooling system. Plus, all three Stop Leak products are safe to use with all colors of antifreeze, are easy to use, and do not require a cooling system flush.

"Prestone has made it so simple to fix three areas prone to leaks – the engine block, the head gasket, and the radiator," said Joseph Mathews, Prestone Chemical Laboratory Technician. "We want people to have an affordable and easy to use solution to avoid repairs that can run thousands of dollars."

“The science behind DuPont Kevlar® allows our customers and licensees to innovate and Dare Bigger in their product design and development,” said Kathy Kowalski, Global Brand, Marketing and Communications Leader, DuPont Protection Technologies.

For do-it-yourselfers, Prestone's line of Triple Seal Protection products made with Kevlar® resin is the ultimate protection against cooling system leaks.
