Most industrial floor failures aren’t actually caused by heavy traffic or chemical spills—they are caused by what is happening under the slab. If you’ve ever seen a high-performance coating blister, delaminate, or succumb to “osmotic pressure,” you’ve seen the results of a weak moisture vapor barrier.

For years, the industry has relied on “shortcuts” in epoxy formulation. Many curing agents use benzyl alcohol as a plasticizer to reduce costs and improve workability. Here is the hot take: Benzyl alcohol is a liability. Over time, it can leach out, leading to film brittleness, “blushing,” and eventual bond failure in moisture-heavy environments.

TERAMINE® 72 was engineered to break that cycle. It is a modified aliphatic, benzyl alcohol-free amine curing agent designed for those who can’t afford a callback.

The Class 1 Advantage: Adhesion Where It Matters

In flooring environments where residual moisture is a constant threat, you need more than just “good” adhesion; you need a Class 1 moisture vapor barrier.

TERAMINE® 72 enables coatings to achieve permeability ratings below 0.1, meeting the rigorous ASTM F-3010 requirements. By stopping water migration through the concrete, it effectively eliminates:

  • Osmotic blistering and delamination
  • Degradation of adhesives
  • Mold and fungal growth under the coating
  • Premature aesthetic failure

Pro-Tip: While a calcium chloride test is standard, using a Class 1 barrier like TERAMINE® 72 acts as your ultimate insurance policy. Its benzyl alcohol-free formulation is what allows it to maintain such a tenacious bond to both dry and damp concrete surfaces.

Performance Benchmarks: TERAMINE® 72 vs. The Field

When choosing a hardener, formulators often struggle with the “Pot Life vs. Cure Speed” trade-off. TERAMINE® 72 bridges this gap by offering a low viscosity for easy leveling without sacrificing the rapid return-to-service that clients demand.

More Than Just a Flooring Hero

While TERAMINE® 72 is a powerhouse for moisture vapor barrier systems, its chemical resistance and color stability make it a versatile tool for the broader industrial market.

Because it cures effectively at ambient and low temperatures, it is a go-to for protective interior linings in:

  • Storage Tanks & Process Containers: Provides a durable barrier against harsh chemicals.
  • Pipes & Metal Equipment: The strong adhesion to metal helps extend the lifespan of critical infrastructure.
  • Food & Beverage Facilities: Rapid turnaround means less downtime for plants that can’t afford to stop production.

The Formulator’s Perspective: Economics & Ease

We know that performance doesn’t matter if the economics don’t work. TERAMINE® 72 is typically used at 38 phr and is optimized for 2:1 by-volume epoxy systems. This gives formulators the flexibility to create high-solids, solvent-free coatings that are both high-performance and cost-efficient.

The result is a high-gloss, low-color finish that retains its appearance even in demanding environments.
