Helix Max Low-Rise Adhesive – Dual Tank is a two-component, construction-grade polyurethane foam roofing adhesive that comes packaged in two-tank sets. It now features a hydrofluoroolefin (HFO) blowing agent that makes it significantly better for the environment than the previous hydrofluorocarbon (HFC) blowing agent.
It still provides the strong adhesion and VOC-free application that the previous formulation was known for. Designed to bond approved roof insulations, thermal barriers, cover boards and fleece-back membranes (TPO, PVC, and PVC KEE) to a variety of roofing substrates.
