Willseal Color Coreseal H is a dense, closed-cell foam typically used for larger movement joints. It has a traffic grade silicone skin on the exposed face, which provides resistance to gasoline and oil. Due to its strong closed-cell structure, it has excellent compression, tension and shear capabilities. It is installed with epoxy and when cured, permanently bonds the Willseal Color Coreseal H in place.
