SUPREME BACKER ROD(PC 2135) is a closed cell polymer based foam filler material with a circular profile. It ensures stronger bonding of sealant with masonry, aluminium or other substrate and helps to maintain desired thickness of sealant at the joint's center. It does not bond with cold applied sealants. SUPREME BACKER ROD is used as back up to sealants to expansion joints and structural glazing systems.
