Introduction to PU Foam Sealant
PU foam sealant, short for polyurethane foam sealant, is a one - component, moisture - curing, multi - purpose construction sealing material. It is mainly composed of polyurethane prepolymer, foaming agent, catalyst, and other additives. When the sealant is sprayed out from the container, it expands rapidly due to the reaction with moisture in the air, filling gaps, joints, and holes. It can bond well with a variety of building materials such as wood, metal, plastic, and glass, providing excellent sealing, insulation, and sound - proofing effects. PU foam sealant is widely used in construction projects, including door and window installation, pipeline sealing, and building insulation.
