Open Cell Polyurethane Backer Rod for Hot and Cold Sealant
Applications.
Open Cell Backer Rod "Tundra Foam" is an ideal
non-gassing backup material which is inserted into construction and
pavement joints to control sealant and caulking depth, create a
backstop to allow proper sealant tooling and configuration, allow
proper sealant airing and yield a proper bond breaker. It is ideal
for non-uniform joint sizes
Open Cell Backer Rod "Tundra Foam" commonly used in
expansion and contraction joints, window glazing, curtain wall
construction partitions, precast assemblies and copings, parking
decks, bridge construction etc. For hot pour where out-gassing and
bubbling is a problem, or where quicker curing is needed.
Open Cell Backer Rod "Tundra Foam" will resist oil,
gasoline and most solvents. This material is odorless, will not
stain and will not adversely adhere to sealant and caulking
material.
Tundra Foam Open Cell Backer Rod is made of a basically inert
material. It is compatible both chemically and physically with
virtually all known hot pour and cold applied sealants, including
silicone and rubber asphalt.
