Foam backer rod joint filler that is used as a backing material for elastomeric and other cold-applied sealants. Helps the sealant assume the optimum shape to prolong service life and acts as a barrier to the flow of sealant through the joint. It will not absorb water and is available in ¼” to 6” diameter. Description HBR helps cold-applied sealants assume the optimum hour glass shape to prolong the sealant service life. It is commonly used in applications such as expansion and contraction joints, curtain walls, construction partitions, parking decks and bridge construction. HBR is an inert material, and therefore, it is physically and chemically compatible with virtually all known cold-applied sealants including self-leveling types. Sealant compatibility should be confirmed by the sealant manufacturer. Compatibility characteristics of sealants in contact with sealant backings can be determined by ASTM C 1087 test method.
