Intumescent Firestop Foam

  • Features
  • Applications

TP20 is a two-component, room-temperature-curing, fire- and condensation-resistant adhesive. Components A and B are packaged separately and are in a liquid state with excellent fluidity. During use, mix them evenly according to the desired ratio and pour them into the holes requiring fire/condensation sealing. After curing, they become a rubber-like substance with excellent elasticity and strength. Under normal circumstances, they effectively block the passage of water, vapor, and other gases. In a fire, they prevent the spread of flames and smoke. Component A is black, and component B is white, making it easier to determine whether the mixture is evenly mixed.
