Willseal Color Coreseal-H is a dense, closed-cell foam 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 that permanently bonds the Color Coreseal-H in place.
