A one component, butyl rubber based product used as a vapor barrier sealant in the joints of cellular glass, polyisocyanurate (PIR), urethane and phenolic foam board stock insulations.

Is primarily used with low temperature insulation to prevent the migration of water and water vapor into the insulation system via butt joints. Also recommended as a bedding compound for the installation of cellular glass insulation. In this application, it protects both the insulation from abrasion and metal surfaces from corrosion.
