Moisture remains one of the most common causes of flooring failure, yet it is often underestimated during system design.
A concrete slab may look dry on the surface, but internal moisture can remain elevated for years. When a coating or flooring system with low permeability is applied over that slab, moisture vapor pressure can build at the interface. Over time, that pressure can lead to blistering, delamination, adhesive breakdown, and premature system failure.
For formulators, this is where curing chemistry matters.
Trans Western Chemicals, in partnership with Pflaumer Brothers, is bringing greater attention to performance-driven raw materials for moisture-challenged flooring systems. One material worth attention in moisture-resistant epoxy systems is TERAMINE 72, a fast-cure epoxy hardener designed for demanding industrial environments.
TERAMINE 72 is a modified aliphatic, solvent-free amine curing agent developed for high-solids epoxy systems. It offers low viscosity, strong flow and leveling, and high-gloss potential, while also supporting strong adhesion to both dry and damp concrete. That last point is especially important in flooring environments where residual slab moisture can compromise long-term bond strength.
Properly formulated epoxy systems using TERAMINE 72 can achieve permeability below 0.1, meeting ASTM F-3010 Class 1 moisture vapor barrier requirements. That level of performance helps reduce the risk of:
- Blistering and delamination
- Adhesive degradation
- Premature aesthetic failure
- Moisture-related maintenance issues
TERAMINE 72 also supports fast gel and effective cure at ambient and lower temperatures, which helps reduce downtime in industrial and commercial settings. This makes it relevant for applications such as manufacturing facilities, warehouses, food processing areas, and other environments where fast return to service matters.
Beyond flooring, TERAMINE 72 also has value in protective interior linings for pipes, storage tanks, process containers, and other metal surfaces where adhesion and chemical resistance are important.
Key performance benefits include:
- Excellent moisture and chemical resistance
- Strong adhesion to damp or dry concrete and metals
- Fast curing with same-day return-to-service potential
- Low viscosity for formulation flexibility
- Good color stability and gloss
- Benzyl alcohol-free composition
- Potential to support Class 1 moisture vapor barrier performance
For chemists formulating industrial flooring and protective coatings, moisture tolerance is no longer an edge-case requirement. It is a core part of system reliability.
If you are working on moisture mitigation primers, epoxy flooring systems, or other demanding industrial coatings, Trans Western Chemicals is ready to help you explore whether TERAMINE 72 is the right fit for your formulation goals.
