Willseal 600 is a UV stable, pre-compressed, self-expanding, flexible, flameresistant joint seal. It is a high-density polyurethane foam that is impregnated with a modified acrylic resin and treated with a pressure-sensitive adhesive on one side for ease of installation. Willseal 600 self-expands to fill the joint creating an elastic, vapor-permeable, weathertight seal.
