Product Data Sheet

Willseal® Seismic is a pre-compressed, self-expanding, open micro-cell polyurethane foam impregnated with a hydrophobic, acrylic polymer and coated with a factory-applied silicone sealant. It is designed to provide a watertight, dust-proof, noise-reducing, thermally insulating, and UV stable primary seal that does not require invasive anchoring for installation.

Features & Benefits

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.
