Zepoxy Clear Hardener
Zepoxy Clear Hardener is a modified cycloaliphatic polyamine curing agent characterized by low
viscosity, clear transparent, and extended pot life. It is designed for use with liquid epoxy resins such
as Zepoxy RER 128 (DGEBA, EEW 190) in the formulation of solvent-free, room-temperature curing
coatings and flooring systems. The cured epoxy system develops excellent mechanical properties
and high durability.

coatings and flooring systems. The cured epoxy system develops excellent mechanical properties
and high durability.
When properly formulated with epoxy resin, Zepoxy Clear Hardener produces smooth, glossy,
bubble-free, and highly transparent surfaces. The cured system exhibits outstanding resistance to
a wide range of chemicals, including acids, alkalis, hydrocarbons, and water. Due to its cycloaliphatic
structure, it also offers superior weathering and UV resistance. Additionally, the product features
low odor, reduced skin irritation potential, excellent clarity, and a very light color, making it suitable
for decorative and high-performance applications.
APPLICATIONS
- Solvent-free, high solids coatings
- Self-leveling floorings
- Primers and screeds
- Transparent coatings
- Chemical resistant mortars and linings
- Electronic potting
