ChemLink SOF-Rod Bi-Cellular Backer Rod

Flexible Foam Rods For Use As Backer For Sealants

Composed of a bi-cellular material, ChemLink SOF®-Rod is a cylindrical, flexible foam rod for use as a sealant backing. ChemLink SOF-Rod is used in common applications such as expansion and contraction joints, window glazing, curtain wall construction partitions, parking decks, bridge construction, modular home gasketing, and log home chinking.

ChemLink SOF-Rod Backer Rod Benefits

Use of SOF-Rod limits the depth of the sealant and prevents excessive sealant use. It also acts as a barrier to the flow of sealant through the joint, helps prevent 3 point bonding, and forces the sealant to take a more optimum shape prolonging sealant service life.

SOF®-Rod may also be used as a gasket or sealing material as per ASTM C 717.

TYPE: B - Per ASTM C 1330. Cylindrical, flexible sealant backings composed of bi-cellular material.

Also reference ASTM C 717 for use as gasket or sealing material.

TYPE: 3 - Per ASTM D 5249. Round rods of various diameters for use with non-sag and self leveling cold applied sealants.

TEMPERATURE LIMITS: -45°F to +160°F.

Chemlink SOF-Rod Backer Rod Compatibility

SOF-Rod is composed of a bi-cellular polyolefin foam. Bi-cellular polyolefin foam is compatible, both physically and chemically, with most cold applied sealants. Compatibility of sealants in contact with backings can be evaluated according to ASTM 1087test Method C.

I spoke with the person in the Technical Support department who listened and understood my complicated circumstances and made the perfect recommendation. I received the product within a couple of days and before the weekend ended, the job was complete and I am very pleased with results. Thank you, Eco Building Products for your support and product recommendation.
