GREEN LINK Adhesive/Sealant is a non-shrinking polyether adhesive/sealant specially formulated to bond the KnuckleHead base to a wide range of roofing membranes including EPDM, PVC, Granulated Modified Bitumen, and TPO (with TPO primer).
GREEN LINK Adhesive/Sealant is a polyether-based, moisture-cure formula that has been used in the construction industry for many years. It has earned a reputation for high performance, adhering to a wide range of roofing membranes including PVC, EPDM, Mod Bit and TPO (with primer) yielding a strong, long-lasting bond that exhibits excellent weathering characteristics. GREEN LINK Adhesive/Sealant is 100% solids and it cures by contact with moisture—no evaporation of solvents, so there is no shrinkage as with many adhesives that lose as much as 30-40% of their volume once solvents evaporate. GREEN LINK Adhesive/Sealant is entirely safe—no risk of fire, explosion, or toxic exposure to workers or building inhabitants. It meets the requirements of California Regs: CARB, BAAQMD, and SCAQMD. It does not contain cancer-causing chemicals listed in California Proposition 65. The VOC content is less than 25 per grams per liter.

GREEN LINK Adhesive/Sealant squeezed out of the base holes functions as “rivets,” which serve to attract moisture, speeding up the curing process. Also, when fully concealed mechanical fasteners are used to mechanically attach the Universal Base, GREEN LINK Adhesive/Sealant can be applied to the fastener heads to form a waterproof seal. It is so effective in this regard it can be used for emergency repairs where it can be applied directly in ponding water to seal a roof leak instantly.
Storage and Handling
GREEN LINK ADHESIVE/SEALANT has a 12-month shelf life from the date of manufacture when stored at 70° F (21° C) and 50% relative humidity. Store original, unopened containers in a cool, dry area. Protect unopened containers from water, heat and direct sunlight. High temperature and high relative humidity may significantly reduce shelf life.
