Willseal® 600 is a pre-compressed, self-expanding foam joint sealant, engineered to perform as a highly flexible, weather-tight, primary or secondary seal in vertical exterior applications. Willseal 600 is specifically designed to provide the ideal foundation for a large variety of wet sealants, such as silicone, polyurethane, polysulfide, and acrylic. Unlike conventional wet sealant and backer rod methods, Willseal 600 is not susceptible to breakdowns caused by excessive or rapid joint movements, thus protecting structures against rain, wind, dust, and sound. Willseal 600 is waterproof to a wind driven rain at 12.5psf (70mph) yet it is vapor permeable, making an optimal addition to any air barrier system, cavity wall joint, and interior partition application.

Willseal 150 is a precompressed, self- expanding polyurethane foam joint sealant that is designed to seal against rain, wind, sound, draft, and dust. Unlike other conventional methods, Willseal 150 is not susceptible to breakdowns caused by excessive joint movements, joint strain, surface contamination, aging, and general tensile stress-caused failures. It does not dry out, shrink, or deteriorate. There's no mixing, no masking, no staining, and no mess. Willseal 150 can be installed under many weather and temperature conditions.

Willseal 250BG is a primary seal for below grade applications where partial or total water immersion is expected. Willseal 250BG is suitable for fresh, ground, sea, and chlorinated water. Developed to perform under extreme conditions in vertical and horizontal applications including water treatment facilities and underground parking structure type expansion joints. It is ideal to discuss all project parameters and requirements with Willseal Technical Support to design the most appropriate system.

Willseal Coreseal is a preformed, compressible system that is impermeable to water and when bonded in place provides a watertight seal. It was developed to meet all applicable standards for compressible sealants and performs under extreme conditions such as those found in vertical and horizontal applications including bridge and parking structure type expansion joints. It provides a watertight, dust-proof, airtight, UV stable, chemically resistant, soundproof, and insulated primary seal. Once installed in the joint, the material adapts to the width of the joint and the irregularities of the substrate, provided such profile changes are not sudden or extreme.

Willseal Color Coreseal 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 in place.

Willseal FR-V is designed to be used in vertical wall installations by itself, but it can be used behind any other expansion joint cover, plate or filler where joint depth allows. Because it is coated on both sides, it can be placed with either side exposed, adding to the versatility and increasing the aesthetic fireproof sealing options.Willseal FR-V is a second generation, unified fire rated, sound, energy, and waterproof sealant system that can be supplied for +/- 25% and +/- 50% joints. Willseal FR-V is not made of thin, unbonded vertical layers that can delaminate with joint shear or thermal shock. In addition to UL 2079, Willseal FR-V has been independent lab tested to ASTM 330, 331, 283 & 547 for water and air penetration. It has been tested and passes TAS 202/203 requirements for hurricane force exposure.

Can be supplied uncoated, coated on one side, or coated on both sides, depending on UL listing. Refer to www.ul.com.
