Green Link sent word of a new adhesive/sealant it’s created specifically for use with its KnuckleHead Rooftop Support System, which we profiled here. Green Link Adhesive/Sealant bonds and seals the KnuckleHead Universal Base and is effective on a wide range of roof surfaces. The new adhesive/sealant has been specially formulated to adhere to PVC, EPDM, TPO, and Mod Bit, as well as the KnuckleHead base itself, which is composed of glass-reinforced nylon.
“The KnuckleHead base is unique in that it can be adhered directly to the roof membrane,” said Ondrej Pekarovic, Green Link design engineer. “While there are some products on the market that effectively bond and seal the KnuckleHead base, Green Link Adhesive/Sealant is the only product that effectively adheres to even the most challenging types of PVC membranes.”
Green Link Adhesive/Sealant is based on polyether chemistry. It cures by exposure to moisture, so it can be applied to damp surfaces and will not shrink upon curing. It will not discolor from UV exposure, can be applied at temperatures as low as 32°F, and is capable of joint movement in excess of 35%. It is available in standard 10.1oz cartridges.
