Willseal Seismic is a one-step primary sealant for exposed areas where color matching is important. It has a puncture resistant, elastomeric coating on the exterior surface, which can be factory colored to match most construction substrates or sealants. The joint is watertight and color matched.
Willseal Seismic is an open micro-cell polyurethane foam impregnated with a hydrophobic, acrylic polymer sealing compound. It is designed to provide a watertight, dust-proof, airtight, UV stable, chemically resistant, sound-proof, and insulated primary seal. Willseal Seismic, by it’s design, is inherently insulating and sound deadening. Willseal Seismic is a monolithic foam sealant that will not delaminate like multi-layer products that are comprised of unbonded vertical foam strips.
Willseal Seismic is used in applications including:
