High Solids Cylinder Adhesive (Low-VOC) | Magna Tack MT-Series
The “Swiss Army Knife” for Industrial Insulation & Construction.
Magna Tack (MT) proves that “Compliant” doesn’t mean “Weak.” While many low-VOC adhesives are watery and slow to dry, Magna Tack is engineered with a Heavy-Duty 42% Solids profile. This is a true industrial contact cement designed for high-speed production lines that cannot afford to wait for weak glues to tack up.
Because it is MIR 50-State Compliant, you get the best of both worlds: The aggressive grab of a legacy solvent glue, with a modern formula that is legal to sell and use in every state—including California.
The Efficiency Math: Why Use a High Solids Cylinder Adhesive?
Efficiency drives profitability. Because Magna Tack contains significantly more rubber and resin than economy sprays, it sits on top of porous surfaces like duct insulations rather than soaking in. This creates a stronger bond with less product.
Manufacturer’s Tech Note: Because of the heavy 42% solids content, standard spray tips may clog or spray unevenly. You must use Tip 6501 or Tip 730116. These specific tips are engineered to atomize the high-density rubber/resin blend into a perfect web pattern. (Both tips come standard with our SPG-AG gun).
- High-Solids (>42%): Delivers a heavier adhesive load per spray. Bridges gaps on porous fiberglass and duct board without soaking in, ensuring a permanent bond.
- Rapid Flash (15-30s): Designed for high-speed production. The solvent flashes off almost instantly, allowing for immediate mating of materials.
- Safety Profile: Despite its strength, MT-LC maintains an ultra-low VOC profile of just 2.45 g/L. This protects user safety and indoor air quality.
Professional Application: Ideal for duct liner, fiberglass insulation, urethane, rubber, glass, and metal-to-metal bonding.

FAQs
Frequently Asked Questions: Magna Tack (MT)
Application & Performance
Q: What spray tip should I use for Magna Tack?
A: Because Magna Tack has a very high solids content (>40%), you must use specific tips to ensure a proper web pattern. We recommend Tip 6501 or Tip 730116. Different tips may cause sputtering, streaming, or uneven coverage due to the thickness of the adhesive.
Q: What is the tack time and open time?
A: Do not wait! Magna Tack is engineered for high-speed production. It flashes off in just 15–30 seconds. Once tacky, you have a short open window of approximately 1 minute to mate the surfaces. If you wait too long, the adhesive will lose its grab.
Q: Can I use this on Styrofoam or Polystyrene?
A: Generally, No. Like most solvent-based industrial adhesives, the carrier solvents can attack low-density polystyrene foam (EPS). However, it is excellent for urethanes, rubber, and fiberglass. Always perform a small patch test before using on sensitive plastics.
Q: Is this a “Contact Adhesive”? Do I spray one side or two?
A: Yes, this is a true contact adhesive. For a permanent, industrial-grade bond, you must spray a uniform web coat on BOTH surfaces (the substrate and the material). Allow 15-30 seconds to tack, then compress them together immediately.
Q: Is Low-VOC adhesive strong enough (High Solids)?
A: Yes. Standard adhesives are often ~20-30% solids, meaning you are paying for solvent that just evaporates. Magna Tack is >40% solids. This means more actual glue stays on the surface, bridging gaps in porous duct liner better and requiring fewer passes to get a strong bond.
Troubleshooting
Q: Why is the spray pattern inconsistent or “spitting”?
A: This usually indicates one of a few things:
- Wrong Tip: You must use Tip 6501 or 730116. Smaller tips cannot handle the high-solids flow.
- Cold Cylinder: The adhesive is too cold. Maintain the cylinder between 60°F – 90°F. If the cylinder is cold, the pressure drops, and the adhesive thickens, leading to a poor spray pattern.
- Clogged Equipment: If the hose or tip sits too long with product not being used, the glue can start to setup. Use universal adhesive remover (UAR-SC) to purge the hose and tip of dry adhesive.
Q: Why is my bond failing?
A: Production Speed. If the bond is failing, you are likely waiting too long. Because this is a fast-tack formula, you must mate the materials within 60 seconds of spraying.
Safety & Compliance
Q: Is Magna Tack Flammable?
A: During Application: YES. The solvent carrier (Methyl Acetate) is flammable. You must keep the spray area free of sparks, pilot lights, and open flames.
After Curing: NO. Once the solvent evaporates (which happens very quickly), the remaining adhesive bond line is non-flammable.
Q: Does this product contain Methylene Chloride or Perc?
A: No. Magna Tack is free of chlorinated solvents, including Methylene Chloride and Perchloroethylene. This makes it a safer, lower-toxicity option compared to older chemical formulas.
Q: Can I sell or use this product in California?
A: YES. Unlike many competitors, Magna Tack is MIR 50-State Compliant. It meets the strict Low-VOC air quality regulations of California (SCAQMD), Utah, and the OTC states, allowing for unrestricted use nationwide.
Q: What is the VOC content?
A: Magna Tack is an Ultra-Low VOC formula containing approximately 2.45 g/L. This is significantly lower than standard flammable contact adhesives, which helps facilities meet “Green Building” and LEED standards.
Logistics & Storage
Q: What is the shelf life of a cylinder?
A: Magna Tack cylinders have a manufacturer warranty of 1 year from the date of manufacture when stored correctly. Always store cylinders off the concrete floor in a cool, dry area. Do not expose to temperatures above 120°F (49°C).
Q: Is this product affected by the EPA “Sunset Dates”?
A: No. While other adhesives (like those containing HFCs or Perc) face bans in 2026/2027, Magna Tack is a future-proof formula. It has no upcoming EPA phase-out dates, making it a secure long-term solution for your inventory.
Q: What sizes are available?
A: The standard size for industrial fabrication is:
- MT-SC (Small Cylinder): A portable 11 lb cylinder. Think of it like a massive aerosol can (holds roughly 13-20 cans worth).
- MT-LC (Large Cylinder): The standard 35 lb shop/job site cylinder.
- MT-200: Industrial 180 lb cylinder for high-volume fabrication runs.
Q: How do I dispose of the cylinder?
A: The MT-LC is a non-refillable DOT 39 cylinder. Once empty, turn the valve open to release any remaining pressure, punch the knock-out plug (if equipped), or follow your local scrap metal recycling guidelines for empty steel pressure vessels. Never incinerate or puncture a pressurized cylinder.

Primary Application. Web spray prevents soak-in. |
| Reflective Insulation (Bubble Wrap) |
✅ RECOMMENDED
Ideal for bonding aluminum-faced bubble wrap to metal ductwork. |

⚠️ CAUTION
Resists plasticizer migration, but high-tension applications should be tested. |
Temperature Warning (The Cold Cylinder Rule):
DO NOT APPLY BELOW 60°F. Cold cylinders lose pressure, preventing the high-solids fluid from atomizing. This results in “spitting” rather than a web spray, causing uneven coverage and weak bonds. Warm cylinder to room temperature before use.
Directions for Low-VOC HVAC Cylinder Spray Adhesive:
MT-SC, LC, 200
1. Preparation & Setup
Step 1: Ventilation. Ensure the area is well-ventilated. Eliminate all ignition sources (pilot lights, sparks).
Step 2: Surface Prep. Surfaces must be clean, dry, and free of oil or grease.
Step 3: Connect Equipment. Attach the hose to the cylinder and the spray gun to the hose. Tighten with a wrench.
Tech Tip: For the Magna Tack 42% Solids formula, you MUST use Tip 6501 or Tip 730116. Standard tips will not create the proper web pattern.
2. Application (The 30-Second Rule)
Magna Tack is designed for speed. Follow the timing closely.
- Spray Technique:
- Hold gun 6-10 inches from surface.
- Apply a uniform web coat to BOTH surfaces (80-100% coverage).
- Move quickly—do not allow adhesive to puddle.
- Flash-Off (Wait Time):
- Wait 15 to 30 seconds.
- The solvent needs to evaporate to become “tacky.”
- Test: Touch with knuckle—adhesive should be sticky but not transfer to skin.
3. Bonding & Cleanup
- Mate Surfaces:
- The Window: You have 1-3 minutes to bond the materials.
- Press surfaces together firmly, applying pressure from the center outward.
- Bond is immediate. Parts can be handled right away.
- Cleanup:
- Turn Off: Close cylinder valve.
- Purge: Trigger gun until only gas comes out to clear the line.
- Flush: If storing for >2 days, attach UAR-SC (Adhesive Remover) to flush the gun/hose and prevent clogging.
