Meet your new non-flammable HVAC adhesives

MEAN GREEN 2.0 - Compliant, Safe, and Built to Perform.

EPA rules around certain chlorinated solvents—like methylene chloride—are reshaping the HVAC adhesive space. For many contractors and wholesalers, true non-flammability isn’t optional; it’s key for safety and insurance. Vapco’s answer: 2 fresh, compliant formulas that keep the speed, strength, and spray you rely on.

Overview of what’s new:

Two updated, non-flammable options: Mean Green and Mean Green Long Tack

  • Both are methylene chloride-free and align with current EPA restrictions
  • Same trusted performance as the original Mean Green in bond strength, coverage, and spray quality

A quick word on safety and industry claims

You may see products marketed as “non-flammable” but looking in the fine print, you'll see that it's only non-flammable when dry. That can be misleading—most risk happens during application and storage. To stay safe and compliant, always check: Flammability classification on the label and SDS Confirmation that it’s methylene chloride-free

Yes. Both Mean Green and Mean Green Long Tack are methylene chloride-free and align with current EPA restrictions on certain chlorinated solvents. For regulatory specifics, consult the product SDS and your local requirements.

Mean Green: Faster workflow. Open time 1–4 minutes; cure 5–6 minutes. Great when speed matters.

Always test your pattern and follow the label/SDS.

Yes. They’re designed to deliver the same trusted performance in bond strength, coverage, and spray quality—now without methylene chloride and maintain non-flammable classifications. Mean Green preforms exactly like you’re used to while Long Tack has a longer open and cure time which can be beneficial for larger jobs or where precision is paramount.

Magna Tack is the value option. It’s flammable and should only be used where site safety protocols allow. It delivers quick tack and a lasting bond at a budget-friendly price point. Preforms exactly how you would expect a flammable solvent based adhesive to preform.

Environmental conditions and substrate porosity can extend or shorten both open and cure times. As a rule of thumb: colder and more humid conditions generally lengthen cure times—in cold environments, keep your cylinder off concrete floors to help regulate tack / cure times. Always follow the label and SDS.
