Helix Max Low-Rise Adhesive Drums

Yes, but it depends on the delivery system. Full spray application is possible using 5-gallon jugs, 15- and 50-gallon drums if the dispensing equipment has high-pressure capabilities. Splatter pattern application is possible when using Tanks only for approved membrane attachment.

Yes. First, there is a maximum 4' x 4' size restriction when installing any insulation board in foam adhesive because they can warp and cup. Heavier cover boards, such as DensDeck Prime and Securock can be installed in 4' x 8' sheets. Another restriction is that the splatter pattern when using tanks is not approved for insulation attachment.

No. PVC is not an approved substrate for Helix Max. In addition, Helix Max is not approved for attachment to existing aluminized, acrylic or silicone coatings.

Original Helix tips do not work with Helix Max.

A continuous layer (full spray) of Helix Max can increase the R-value .20 to .50.

Helix Max does not stick to new, or previously unexposed, asphalt that has a shiny appearance. Whenever shiny asphalt is encountered, the asphalt must be primed with AeroWeb Low-VOC Adhesive prior to the installation of Helix Max.

Helix Max is blue. Helix was gray.

Yes, absolutely! Each manufacturer designs mixing tips to create the desired 1-to-1 ratio based on the product properties. Helix Max mixing tips must be used with the Helix Max Gun Assembly or Cartridges. Failure to use Helix Max mixing tips results in off-ratio mixing and the foam will not properly rise.

No, dispensing guns may be purchased through ABC Catalog.

Helix Max allows for “walking in” boards then rolling them in with a 150# roller. Ballasting of the boards may be beneficial during installations in windy conditions, however either application method is acceptable to Mule-Hide.

When installed in a full spray application, Helix Max provides 33-50% better puncture resistance.

The substrate and ambient temperature must be above 25°F when using Helix Max. If temperatures are below 50°F, the adhesive must be kept above 70°F during application. Heated tank blankets (not band heaters) are recommended to keep the adhesive warm during application at 50°F or lower.

As a general rule, material costs to use Helix Max is around 5 to 6 times more expensive than using screws when one layer of insulation is installed. Unlike mechanically fastening insulation where only the top layer is fastened, each individual layer must be adhered when using Helix Max. However, some of the major benefits to using Helix Max Adhesive can greatly decrease costs in other areas of the project, such as: • Reduced labor compared to standard fastening into concrete, gypsum, cementitious wood fiber (Tectum), and lightweight concrete roof decks

Helix Max has a longer open time than Helix. This enables the contractor to have more time to set the boards and membrane in the adhesive before it loses string, or tack.

When Helix Max is dispensed, it should be allowed to rise for approximately 1.5-2 minutes until it becomes stringy when pinched between gloved fingers. Once the adhesive has “string,” open time begins and the insulation or membrane can then be set in the adhesive. The open time is approximately 3-3.5 minutes. Open time expires once the adhesive skins over on the top and is no longer stringy.

Helix Max has a shelf life of approximately 12 months when stored in an upright position at 50°-90°F in its original unopened container. Storage temperatures above the recommended range shorten shelf life. Do not store in direct sunlight or temperatures higher than 90°F, such as using it for tarp weight on a roof. Helix Max should be stored in a covered, secure location. Keep from freezing. Product stored below 50°F must be given sufficient time (minimum 24 hrs.) for the adhesive to warm up prior to use.

Only fleece back membranes can be adhered using Helix Max. Currently, Mule-Hide offers TPO, PVC, and PVC KEE HP in Fleece Back configurations.

Adhesion tests are scheduled through your Mule-Hide Territory Manager.

Mule-Hide will have more extensive listings of assemblies with UL and FM.
