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.
Monolithic foam sealant that will not delaminate like multi-layer products that does not rely on silicone coating or the adhesion of a field applied bead of sealant to provide a watertight seal. Independent lab tested to ASTM 330, 331, 283 & 547 for water and air penetration. Willseal Color Coreseal H is by it’s design inherently insulating and sound deadening. It’s unique foam profile reduces tension at the bond line and allows for a much longer service life than competitive products. (See cyclical test results for proof of its resistance to compression set).
