Description

Its Triple Seal Protection utilizes effervescent beads that break down to reach the leak source. DuPont™ Kevlar® resin then forms a fibrous web that binds to metal, and an acrylic polymer hardens the seal to make it permanent. This advanced formulation also helps speed leak-seeking chemicals through the system to maintain optimal cooling system performance.
