A sealant is a substance used to block the passage of fluids to prevent leakage and air penetration. Commonly made from materials like silicone, polyurethane, or acrylic, sealants are flexible and durable, forming a weatherproof, non-porous barrier. On the other hand, adhesives are used to bond materials together by surface attachment, offering both strength and durability. It can be permanent or temporary and is formulated from epoxy, silicone, or acrylic.
