BELOIT, Wis. — Mule-Hide Products Co.’s new Helix® Max Low-Rise Adhesive is a low-rise, environmentally-friendly adhesive that delivers quick, low-odor application and strong adhesion while also offering greater elongation and tensile strength.

Helix Max is a two-component, construction-grade polyurethane foam adhesive designed to bond approved roof insulations, thermal barriers, cover boards and fleece-back single-ply membranes (TPO, PVC and PVC KEE) to a wide variety of roofing substrates. It replaces Mule-Hide Helix Low-Rise Adhesive, which has been discontinued.

Helix Max can be applied in colder temperatures than its predecessor to help prevent weather-related delays. The original Helix's substrate and ambient temperature had to be above 32 degrees Fahrenheit to be applied. When applying Helix Max, the threshold has been lowered to 25 degrees.

Mule-Hide said like its original Helix, Helix Max is applied in a single step. It also has a longer open time, giving contractors more time to set boards and membrane. Both parts of the adhesive are ready to use from the container and are applied simultaneously in a one-to-one ratio through a static mix tip. It eliminates the need for mechanical fasteners, maintaining a continuous vapor retarder, preventing thermal bridging and protecting the structural integrity of the roof deck.

The company said Helix Max has an elongation of up to 150 percent and increased tensile strength to ensure an exceptionally strong bond. Additionally, its strong wind uplift resistance means Helix Max can be used on taller buildings and in higher wind zones.

Full-spray splatter application is possible with the proper equipment, and when used to install fleece-back membranes, provides hail resistance and improved energy efficiency. Puncture resistance is increased by 33 percent to 50 percent when full-spray splatter application is used. A continuous layer of Helix Max increases a roofing system’s R-value by 0.20 to 0.50 per layer.

Helix Max comes in a five-gallon jug packaging option for use with low-pressure spray equipment. These plastic jugs are easily moved around the jobsite and will not dent during transportation or if dropped. Handles on the tops and sides of the jugs make them easy to load onto dispensing equipment. The containers resist moisture, preventing contamination of the adhesive, and unlike traditional “bag-in-a-box” packaging, they will not fall apart when wet.

Helix Max is low-odor and contains no volatile organic compounds (VOCs), chlorofluorocarbons (CFCs) or hydro chlorofluorocarbons (HCFCs), making it crew-, building occupant- and environment-friendly.

In addition to the new five-gallon jug sets, Helix Max is available in twin-pack cartridges, tanks and 15- and 50-gallon drums.
