What Is Foam Sealant?
Foam sealant is a versatile sealing material designed to close gaps and joints in buildings and machinery, effectively blocking water and air while improving insulation and noise reduction.
This sealant starts as a liquid and is applied or injected into spaces, where it reacts with air moisture to cure into a flexible, elastic form. This transformation allows it to fill voids, seal tightly, and bond well to various surfaces.
Common materials for foam sealants include polyurethane, silicone, acrylic, and latex. Polyurethane types are praised for their robustness and adaptability to both indoor and outdoor conditions. Silicone-based sealants stand out for their exceptional resistance to weather and high temperatures, ideal for humid climates and areas exposed to extreme heat.
