GREEN LINK ADHESIVE/SEALANT is a moisture curing, polyether, elastomeric joint sealant designed for application in damp, dry or cold climates. Curing occurs in wet or dry climate conditions and at temperatures as low as 32° F (0° C).

GREEN LINK ADHESIVE/SEALANT is solvent free and contains no isocyanates. It will not shrink upon curing, will not discolor when exposed to UV light, and will not “outgas” or bubble on damp surfaces.

GREEN LINK ADHESIVE/SEALANT has excellent adhesion to most construction materials and resilient elastomeric properties. It is formulated to bond to substrates such as PVC, Kynar®-coated metal, concrete, block, brick, stone, masonry, aluminum, galvanized metal, wood, glass, fiberglass FRP or EPS foam.

GREEN LINK ADHESIVE/SEALANT is available in gray.


GREEN LINK ADHESIVE/SEALANT is supplied in 10.1-ounce cartridges and can be ordered individually or in cases of 12 or 24. One cartridge will cover approximately 18 to 20 linear feet with a 3/8-inch (9.53-mm) bead.


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.

GREEN LINK Adhesive/Sealant and KnuckleHead Base


  1. Remove: all dirt, oil, loose paint, frost and other contamination from all working surfaces. Do not use petroleum solvents such as mineral spirits or xylene. Horizontal applications may require tooling.
  2. Store sealant between 60° F – 80° F (16° C – 27° C) prior to installation for easy gunning and tooling. Sealant may be applied below freezing temperatures.
  3. Apply using a standard caulking gun. Do not open the cartridge until you are ready to apply the sealant.
  4. Apply the sealant using consistent, positive pressure to force sealant into the joint, creating a bead approximately 3/8 inch (9.53 mm) in diameter.
  5. If tooling is needed, do so within 15 minutes of application. Tool the sealant to create a concave joint shape to shed water and ensure maximum adhesion and coverage.
  6. Sealant will skin over within 30 minutes of application. The time may vary depending on humidity and temperature at the time of application.
  7. Sealant is paintable (latex and/or acrylic-based paints) after 24 hours.


  1. Wet sealant should be cleaned by wiping with a clean, dry cloth.
  2. If any sealant remains, then a rag dampened with denatured alcohol, or mineral spirits can be used to remove the remaining residue.


  • Read Safety Data Sheets (SDS) prior to using.
  • Keep away from children.
  • Wear proper personal protective equipment, such as gloves and eye protection, per the SDS.
