willseal 600 is a precompressed, self-expanding polyurethane foam joint sealant that is designed to seal against rain, wind, sound, draft and dust.
It has a very strong resistance to wear and tear caused by excessive joint movements, joint stain, surface contamination, aging and general tensile stressed-caused failures. It will not dry out, shrink or deteriorate. With its simple installation, willseal 600 is a quick easy way to seal under many weather and temperature conditions.
willseal is made of an open cell polyurethane flexible foam impregnated with a flame retardant modified acrylic. Supplied precompressed with PSA on one side. Black or Grey colors available.
