With the growth of industrial facilities, warehouses, manufacturing plants, and commercial buildings in the Middle East and Southeast Asia, epoxy flooring systems are increasingly used in production areas, logistics centers, and parking facilities.

However, epoxy floor coatings in hot and humid environments may face challenges related to poor adhesion and coating durability. Factors such as moisture exposure, substrate conditions, temperature changes, and daily mechanical stress can influence the long-term performance of flooring systems.

For industrial flooring applications, the selection of epoxy hardener is an important part of formulation design because curing chemistry affects properties such as adhesion, flexibility, water resistance, and mechanical performance.

Epoxy flooring systems are typically based on two-component formulations, where epoxy resin reacts with a curing agent to form a cross-linked coating structure.

Different epoxy hardener technologies provide different performance characteristics. For humid regions and demanding industrial environments, formulators usually consider several factors:

Concrete flooring requires strong bonding between the coating layer and the substrate. Surface conditions, moisture levels, and application environment can influence coating adhesion.

Polyamide epoxy curing agents are widely used in industrial coating applications due to their balanced adhesion, flexibility, and protective properties.

Industrial floors are exposed to continuous traffic, equipment movement, cleaning processes, and chemical contact.

Therefore, coating durability depends not only on resin selection but also on the compatibility between epoxy resin and hardener. A properly selected curing agent helps formulators develop flooring systems with balanced mechanical properties and environmental resistance.

Polyamide epoxy curing agents such as DH-115 are designed for industrial epoxy systems where adhesion, flexibility, water resistance, and mechanical properties are important considerations.

According to the technical data sheet:

DH-115 provides a solid content of minimum 99%, supporting high-solid epoxy formulation development.

Its amine number range of 190–230 mg KOH/g provides a defined reference for curing activity adjustment.

The viscosity range of 8,000–20,000 cps at 40℃ offers formulation flexibility for industrial coating applications.

The TDS also provides curing data at 5℃ with a 200μm wet film thickness, which can be used as a reference when evaluating lower-temperature application conditions.

These technical parameters allow flooring manufacturers to select and adjust formulations based on actual project requirements rather than relying only on general product descriptions.

As industrial construction and infrastructure projects continue to develop, epoxy flooring requirements are moving beyond basic appearance and focusing more on long-term service conditions.

For high-humidity, high-temperature, and industrial environments, epoxy hardener selection should consider:

• Concrete substrate conditions
• Temperature and humidity during application
• Floor usage requirements
• Chemical exposure conditions
• Construction schedule requirements

By optimizing the combination of epoxy resin and curing agent, flooring manufacturers can develop coating systems better suited for regional environmental conditions.
