Directions for Magna Tack Low VOC HVAC Duct Liner Spray Adhesive:
Pre-Application Checklist: Ensure both surfaces are clean, dry, and free of oil, dust, or grease. Shake the can vigorously. Maintain the optimal application temperature for the adhesive between 60°F and 90°F (15°C and 32°C).
-
Application: Hold the can 6–10 inches from the surface. Spray in a sweeping, side-to-side motion for even coverage.
-
For Permanent Contact Bonding: Apply the wide web spray evenly to both surfaces to be joined. Allow a 1–3 minute flash time for 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.

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.

White Paper
Achieving 50-State Compliance and 200°F Reliability: The New Standard for HVAC Duct Liner Adhesives
1. Executive Summary: Compliance & Performance Without Compromise
The HVAC industry is often forced to choose between strict VOC compliance and high-demand thermal performance. Magna-Tack Low VOC Adhesive eliminates this trade-off. Utilizing proprietary, advanced chemistry, it delivers guaranteed 200°F (93°C) thermal stability and superior adhesion while maintaining 50-State compliance (4 g/L VOC).
This white paper details how this adhesive addresses the three biggest pain points for modern HVAC contractors: regulatory risk, high-heat failure, and unreliable bonds on complex new insulation materials.
2. Introduction: The Changing Landscape of HVAC Adhesion
Modern HVAC contractors face unprecedented challenges driven by environmental regulations and evolving material science. Adhesives that worked reliably a decade ago now pose significant business risks:
- The Regulatory Problem: Using an adhesive above the 80 g/L VOC threshold exposes contractors to potential fines.
- The Material Problem: Modern duct liner often uses Polyethylene (PE) or foil facings, which standard adhesives fail to grip, leading to call-backs.
- The Safety Problem: Older adhesives rely on highly toxic solvents like Methylene Chloride or Toluene, increasing liability.
3. The Technical Deficiencies of Traditional Adhesives
Compliance vs. Performance
Generic, low-VOC aerosols often result in **poor coverage yield** and a weak bond that suffers **creep** (slow separation) when duct temperatures exceed 150°F (66°C), leading to insulation collapse.
The PE Surface Challenge
Standard synthetic rubber formulations fail to achieve a true **chemical weld** on **low-surface-energy** materials like PE and foil facings, resulting in a weak, mechanical bond that fails easily.
4. The Magna-Tack Solution: Engineered for Modern Compliance
The Chemistry of Compliance
Magna-Tack achieves an **ultra-low VOC content of 4 g/L** using a non-chlorinated solvent base of **Methyl Acetate/N-Hexane**. This ensures immediate, risk-free compliance on any job site.
The Dual-Action Resin Advantage
The proprietary **VAPCO Dual-Action Poly-Tack Resin Blend** is chemically engineered to form a permanent bond on low-surface-energy materials, ensuring the insulation facing is securely locked to the metal substrate.
Reliable Thermal Integrity
The resin system is certified to maintain bond integrity from **-20°F (-29°C) up to 200°F (93°C)**. This stability ensures insulation will not sag or detach in high-heat attic or supply duct applications.
