HBR XL Cross-Linked Closed Cell Backer Rod

Experience unmatched sealing efficiency with Nomaco HBR XL Cross-Linked, Closed Cell Polyethylene Backer Rod. Engineered for both building envelope and concrete construction, HBR XL serves as a versatile barrier, limiting the depth of both hot-pour and cold-applied sealants while preventing excessive usage.

**PERFORMANCE:** 
Nomaco HBR XL facilitates proper shape factor development of cold-applied sealants, extending their service life by acting as a bond breaker to allow joint movement without compromising sealant integrity. Ideal for expansion joints, curtain walls, and more, it ensures precise application and minimizes wastage.

**VERSATILE COMPATIBILITY:** 
Crafted from inert materials, Nomaco HBR XL boasts broad compatibility with hot-pour and cold-applied sealants, including self-leveling types. Its cross-linked, closed-cell structure ensures long-term performance without the need for a separate bond breaker, simplifying installation and maintenance.

**INSTALLATION:** 
Prior to installation, ensure joints are thoroughly cleaned as per sealant manufacturer’s recommendations to optimize bond strength. Nomaco HBR XL should be installed at the recommended depth using a blunt tool, with careful attention to size selection to prevent over-compression or stretching. Sealant compatibility can be confirmed through ASTM C 1087 test method.
