Expandable Seal®


One Component, Solvent Free Polyurethane based Adhesive


Features & Benefits


Expandable seal is a solvent free, onecomponent, polyurethane adhesive, with a thixotropic structure which makes the adhesive suitable for vertical application.The adhesive cures through reaction with moisture from the substrate and forms a strong, durable, water-resistant connection. It is slightlyexpandable and, therefore, offers complete sealing and provides thermal insulating properties.


Can be applied on:

  • wood
