Willseal Color Coreseal V is a dense, closed-cell foam typically used for larger movement joints. It has a colorized silicone skin on the exposed face, which provides a chemically resistant, puncture resistant and waterproof joint. Due to its strong closed cell structure, it has excellent compression, tension and shear capabilities. It is installed with a lubricating sealant that facilitates installation and when cured, permanently bonds the Willseal Color Coreseal V in place.
