Helix Max Low-Rise Adhesive
Does Helix Max Adhesive look different than the Helix?
Helix Max is blue. Helix was gray.
How cold can it be when using Helix Max?
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.
Will MHP provide the same rated systems with HelixMax that it had with Helix?
Mule-Hide will have more extensive listings of assemblies with UL and FM.
Will Mule-Hide still offer Helix?
No. Current inventory will be depleted, and the Helix product will be discontinued.
Are full spray and splatter pattern available with Helix Max?
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.
What is open time?
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.
Is the open time the same as with Helix?
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.
Does all of the asphalt on the deck need to be removed prior to using Helix Max?
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.
How much more expensive is it to attach insulation with Helix Max versus fasteners?
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
Does it matter what kind of tips are used on the gun or cartridge?
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.
Can I use my leftover Helix tips?
Original Helix tips do not work with Helix Max.
What membranes can be adhered with Helix Max Adhesive?
Only fleece back membranes can be adhered using Helix Max. Currently, Mule-Hide offers TPO, PVC, and PVC KEE HP in Fleece Back configurations.
Can Helix Max adhere directly to an existing PVC single ply membrane?
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.
Are there restrictions for insulation 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.
What is the shelf life of Helix Max?
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.
Who does adhesion tests?
Adhesion tests are scheduled through your Mule-Hide Territory Manager.
How can Helix Max provide increased puncture resistance in Fleece Back systems?
When installed in a full spray application, Helix Max provides 33-50% better puncture resistance.
Can the R-Value of the roofing system increase with Helix Max?
A continuous layer (full spray) of Helix Max can increase the R-value .20 to .50.
Does Mule-Hide sell dispensing guns?
No, dispensing guns may be purchased through ABC Catalog.
Helix requires “ballasting” of the boards, is this required with Helix Max?
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.
