Pu Multifunction Foam Sealant

​Expansion: Its most defining feature is its ability to expand significantly (often 2-3 times its original volume) to fill irregularly shaped voids. This makes it highly effective for sealing hard-to-reach areas and providing an airtight barrier. ​Adhesion: It bonds extremely well to most common building materials, including wood, concrete, metal, brick, and masonry. ​Insulation: The cured foam has a closed-cell structure that provides excellent thermal and acoustic insulation. This helps to reduce energy costs by preventing drafts and heat transfer, and it also dampens sound, making it effective for soundproofing.
