Low VOC HVAC Duct Liner Spray Adhesive:
Magna Tack MTA-1
Precision Formulated for Compliance and Industrial Grade Strength
Magna Tack is not a general-purpose adhesive; it is an engineered Ultra-Low VOC, (0.9 g/L), HVAC Contact Adhesive specifically formulated to repair insulation and duct systems. Utilizing our proprietary resin technology, the adhesive delivers a high-solids (35%+) web spray for maximum yield and provides a permanent bond with superior thermal stability up to 200°F service temperature. As a result, the formula ensures immediate and long lasting, high-strength adhesion while meeting the most stringent air quality and safety codes nationwide.
| KEY FEATURE / SPECIFICATION |
TRADE BENEFIT / RESULT |
| Ultra-Low VOC (0.9 g/L) (SCAQMD 1168 Compliant) |
Project Confidence: Meets the strictest air quality codes for compliant use in schools, hospitals, and LEED-certified projects. 50-State compliant aerosol. |
| Non-Carcinogenic Solvent Base |
Reduces job-site safety liabilities; Free of restricted solvents like Methylene Chloride and Toluene. |
| Dual-Action Poly-Tack Resin Blend |
No Peel-Back: Ensures chemical adhesion to difficult low-energy plastics like bubble-wrap / bubble foil or fiberglass that generic glues fail on. |
| High Solids Content (30% – 40%) |
Superior Yield and Performance: Delivers more active glue per can, lowering cost-per-job and maximizing coverage area. Typical adhesives only use 20% solids. |

Reliable in Heat: Prevents bond failure and “creep” in unconditioned attic spaces or high-heat supply ducts. |
| Fast-Flash Solvent Base (1-3 min) |
Rapid Installation: Allows surfaces to be mated quickly, accelerating project completion rates. |
| Versatile Applications & Strong Bonds |
Creates permanent bonds on primary substrates: fiberglass, urethane, rubber, duct board, and bubble-wrap / bubble foil. |
| Web Spray Pattern |
Controlled Coverage: Reduces overspray and ensures the glue sits on the material surface instead of soaking in, maximizing bond strength. |
| Waterproof, Flexible, and Transparent |
Maintains bond integrity against moisture, accommodates thermal movement, and cures clear for a professional, non-staining finish. |
| Easy Cleanup |
Cleans up quickly with standard mineral spirits, reducing labor time and hassle on the job site. |

Directions for Magna Tack Low VOC HVAC Duct Liner Spray Adhesive:
Pre-Application Checklist
- Warning: Do not use on Polystyrene, Styrofoam, or any EPS/XPS foam, as this aggressive solvent formula will dissolve the material.
- Ensure both surfaces are clean, dry, and free of oil, dust, or grease.
- Shake the can vigorously before use.
- Maintain the optimal application temperature for the adhesive between between 60°F and 90°F (15°C and 32°C).
Application
- Hold the can 4–8 inches from the surface. Spray in a sweeping, side-to-side motion for even coverage.
- For Permanent Contact Bonding: Apply the wide Green Web Spray evenly to both surfaces to be joined. Allow a 30-60 seconds flash time for the fast-evaporating solvents to dissipate, then mate the surfaces and apply firm pressure.
- For Temporary Bonds: Apply adhesive to one surface only and allow it to become fully tacky before applying the material.
- Prevent Clogging: Immediately after use, invert the can and spray a few short bursts to clear the valve. Wipe away any adhesive buildup around the nozzle opening while wet.
Stop settling for low solids and low performance aerosol contact adhesives, Choose Magna Tack (MTA-1): End bond failure and slow application. Choose the Ultra-Low VOC 0.9 g/L adhesive engineered for maximum yield and proven 200°F thermal stability.
Trust Magna Tack for professional, compliant results.
FAQs
Compliance and Safety
Q: How low is the VOC content of Magna Tack, and is it truly 50-State Compliant?
A: Magna Tack is an ultra-low VOC adhesive, containing only 0.9 g/L of Volatile Organic Compounds. This is significantly below the 80 g/L limit for contact adhesives under SCAQMD Rule 1168, ensuring full 50-State compliance for use in all commercial, residential, and green building projects (including those requiring LEED contribution).
Q: Does this adhesive contain Methylene Chloride or other restricted solvents?
A: No. Magna Tack uses a specialized Methyl Acetate/N-Hexane solvent base and is formulated to be free of ozone-depleting and carcinogenic restricted solvents, including Methylene Chloride and Toluene. This reduces job-site safety liabilities.
Performance and Adhesion
Q: Will Magna Tack bond polyethylene (PE) bubble foil insulation to metal ductwork?
A: Yes, absolutely. Magna Tack utilizes the proprietary VAPCO Dual-Action Poly-Tack Resin Blend, which is chemically engineered to bond to low-surface-energy plastics like Polyethylene and foil facings. This overcomes the major failure point of generic adhesives that struggle to stick to PE.
Q: What other primary substrates can this adhesive be used on? A: Magna Tack is engineered primarily for Fiberglass Duct Liner (1.5 lb to 3 lb density) and Galvanized Steel. It also forms strong, permanent bonds on rubber foam (K-Flex/Armaflex), urethane, duct board, and most porous and non-porous surfaces. It is also designed to grip reliably on uneven surfaces.
Q: What is the maximum service temperature the cured bond can withstand?
A: The Magna Tack bond is certified to maintain its integrity up to a service temperature of 200F. This thermal stability ensures that the adhesive will not fail, creep, or degrade in hot supply ducts, plenums, or unconditioned attic spaces.
Application and Troubleshooting
Q: How do I ensure my spray tip doesn’t get clogged after use?
A: To prevent the adhesive tip from clogging (or “sputtering”) due to dried resin, you must clear the valve and nozzle with propellant immediately after use. Wipe away any adhesive residue or buildup from around the nozzle opening while the solvent is still wet.
Q: What is the flash time needed for a permanent bond, and can I use it for temporary bonds?
A: For a permanent bond, apply an even coat to both surfaces. Allow a flash time of 1 to 3 minutes until the adhesive is tacky but does not transfer to your finger (the Knuckle Test). Then mate surfaces firmly. For a temporary or repositionable bond, apply a single, light coat to only one surface and allow it to fully dry for 5 to 10 minutes before mating.
Q: Is Magna Tack foam-safe (e.g., for Styrofoam or EPS)?
A: No. Magna Tack uses a high-strength solvent base which will dissolve low-density polystyrene and extruded polystyrene (EPS/XPS) foams. Use a foam-safe, water-based adhesive for those substrates.
Q: What is the difference between handling strength and full cure time?
A: Handling Strength (3-12 hours) is the time until the bond can withstand manipulation and light stress. Full Cure Time (24 Hours) is the time required for the adhesive to completely off-gas all residual solvents and achieve its maximum chemical resistance and full thermal stability.
Q: What makes Magna Tack a high-yield adhesive compared to alternatives?
A: Magna Tack has a verifiable high solids content of 30 percent to 40 percent by weight. This means less solvent and more active adhesive are delivered per can, resulting in a superior coverage rate and requiring fewer cans per job compared to standard 20 percent solids aerosols.
Q: What is the recommended method for cleaning up uncured adhesive?
A: Uncured Magna Tack can be cleaned up effectively using standard mineral spirits or lacquer thinner. Ensure cleanup is done while the adhesive is still wet. For preventing nozzle clogs, invert the can immediately after use and spray until the solvent runs clear.
Q: Can I use this aerosol adhesive for high-heat applications like automotive headliners?
A: While certified to 200°F for ductwork, we recommend caution for vehicle headliners. Our solvent base (Methyl Acetate/N-Hexane) is highly effective, but it may chemically attack certain vehicle-grade vinyls, thin plastics, or Styrofoam/EPS foam, which requires specialized foam-safe adhesives. For high-heat vehicle applications, we strongly recommend testing a small, inconspicuous area first, as sustained internal vehicle temperatures can sometimes exceed 200°F.
