KnuckleHead 3004-GLGR 10.2oz Grey Roof Adhesive (1 tube) 

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.
