HF-8330L: Cost-Effective Cycloaliphatic Polyamine Adduct for Ambient-Cured Epoxy Coatings

In epoxy coatings, achieving the right balance between cost, application properties, and cured-film performance is often a key challenge for formulators. HF-8330L cycloaliphatic polyamine adduct epoxy curing agent is designed to provide an effective balance of performance and cost for ambient-cured epoxy coating systems.

HF-8330L features low viscosity, making it easier to formulate and process while supporting good flow and leveling characteristics. It can also help formulators optimize the application properties of epoxy coating systems without unnecessarily increasing formulation complexity.

Typical properties:

Viscosity at 25°C: 300-700mpas

Amine Value: 250-350 mg KOH/g

Active Hydrogen Equivalent: 112 g/eq

Recommended Use Level (EEW=190): 60 phr

Typical handling properties:

Gel Time (100g mix at 25°C ): 40-60 minutes

Thin Film Set Time at 25°C: 3-6 hours

Hardness Shore D at 25°C (24h): 80D

After room-temperature curing, HF-8330L can provide good film hardness and excellent surface gloss, making it suitable for coating systems where both mechanical performance and surface appearance are important. When properly formulated, its low viscosity can also contribute to good application characteristics and a smooth coating surface.

The combination of low viscosity, efficient room-temperature curing, good early hardness, and high-gloss surface appearance makes HF-8330L a practical option for formulators seeking a cost-effective curing agent for epoxy flooring and industrial coating applications.

For formulators developing room-temperature curing epoxy systems, HF-8330L offers a versatile curing solution that can help achieve a balance of processing efficiency, surface appearance, mechanical performance, and cost competitiveness.

At Highfar, we continue to develop epoxy curing technologies that enable coating manufacturers to achieve reliable performance while maintaining competitive formulation costs. HF-8330L is one of our solutions for customers looking for a cost-effective cycloaliphatic epoxy curing agent without compromising key coating properties.
