Mule-Hide Products Co. now offers Helix Low-Rise Adhesive in 15-gallon pony kegs and 50-gallon drums for use in completing larger jobs. According to the manufacturer, Helix Low-Rise Adhesive provides quick, clean adhesion of approved roof insulations, thermal barriers, cover boards and fleece-backed single-ply membranes to a wide variety of acceptable roofing substrates. The two-component, construction-grade polyurethane foam is applied in a single step, saving crews time and hassle.
Both parts of the adhesive (Part A and Part B) are ready to use from the container – no mixing required – and are applied simultaneously in a 1:1 ratio through a static mix tip. The adhesive is applied in continuous ribbons or beads spaced 4, 6 or 12 inches apart, depending on the project and code requirements. There is no overspray. The adhesive cures fully in just minutes.
A pony keg covers approximately 2,350-7,000 square feet of roof and a drum covers approximately 8,350-25,000 square feet of roof, depending on bead spacing and substrate properties. Containers of Part A and Part B are priced separately but must be purchased as a set.
According to the company, the adhesive is odorless and solvent-free and contains no volatile organic compounds (VOCs), chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs), making it crew-, building occupant- and environment-friendly.
The adhesive eliminates the need for mechanical fasteners, maintaining a puncture-free vapor retarder, preventing thermal bridging and protecting the structural integrity of the roof deck. The adhesive provides superior wind uplift resistance, allowing it to be used on taller buildings and buildings in higher wind zones. In addition, it provides exceptional hail resistance when used as an adhesive for fleece-backed membranes.
In addition to the pony kegs and drums, Helix Low-Rise Adhesive remains available in cartridge twin-pack tubes (covering approximately 125-400 square feet of roof) and two-tank sets (covering approximately 1,000-3,000 square feet of roof).
