THE PROBLEM
Most duct liner adhesives are built for general construction, not HVAC specific applications. They use low-solids formulas (around 20%) padded with solvents, which means you’re spraying more carrier than glue. The bond might look fine on install, but a few months later in an unconditioned attic or crawl space, the liner starts peeling back. Lot’s of alternatives don’t have the thermal stability or the solids content to survive real-world conditions.
WHY MAGNA TACK WINS
Engineered with an Ultra-Low VOC, Magna tack is 50 state compliant and designed specifically for HVAC applications. It has a dual action Poly-Tack resin blend that delivers 35%+ solids content in the aerosol and an even higher 42% solids in the cylinders. It bonds to difficult low-energy substates that generic adhesives fail on – bubble wrap, bubble foil, fiberglass and more without peel back. The 200-degree thermal stability rating means the bond holds in unconditioned spaces and high-heat supply ducts. It’s meets the strickets air qualty codes for compliant use in schools, hospitals, and LEED-Certified projects.
BEST USED FOR
Duct liner & Insulation Repair – the primary application. Reattach peeling fiberl-gass liner, secure loose wraps and repair bubble foil or bubble wrap insulation that generic adhesives can’t hold.
Code-Restricted Environments – the low VOC rating meets SCAQMD rule 1168 and every state and local air quality regulation in the country…and it still sticks.
New Construction & Duct Fabrication – bond duct board, fiberglass, urethane, and rubber substrates during fabrication. The high-solids web spray in the aerosol or cylinder maximizes coverage area and the fast flash time keeps the install moving.
What’s in your sample box?
Your kit includes an MTA-1 the 12oz portable aerosol, designed for service calls, rooftop repairs and smaller installations. For large scale new construction, Magna Tack is available in pressurized cylinders, 1 gallon, 5 gallon and 55 gallon bulk containers for brush, spray gun or rolling table applications.
Do not use on polystyrene, styrofoam, or any EPS foam – the solvent base will dissolve them.
