ZH-713

• ZH-713 is a polyamide epoxy hardener, typically a light yellow to dark yellow liquid
• The characteristic of polyamide hardeners is their reaction with epoxy resin to form a stable polymer network, providing high adhesion and elasticity.

Main features:

Creates strong but not brittle cross-links, resulting in a curing film with good toughness and impact resistance.

This property makes the product suitable for surfaces requiring resistance to cracking/peeling under mechanical vibration.

Excellent adhesion to a wide range of surfaces such as metals, concrete, and composites.
Higher resistance to moisture, corrosion, and certain chemicals compared to many conventional amine-based hardeners.

It typically cures more slowly than amine-based hardeners, resulting in a longer pot life and making it convenient for large-scale applications.

Typical Applications

Polyamide epoxy hardeners like ZH-713 are widely used in industrial applications requiring high durability and adhesion:

✅ Industrial Protective Coatings
Epoxy paints protect metal surfaces, gutters, and outdoor structures.
Anti-corrosion coatings in environments exposed to water, salt spray, etc.

✅ Industrial Floor/Concrete Subfloor Coatings
Epoxy paints for traffic areas, factories, warehouses, parking lots, etc., due to their load-bearing capacity, slip resistance, and abrasion resistance.

✅ Industrial Adhesives & Technical Adhesives
Adhesives for bonding materials such as metal, concrete, wood, composites, and plastics, thanks to their high adhesion and good mechanical properties.

✅ Composite and Repair Materials
Applications as substrates, grouts, and epoxy mortars in structural repair and lightweight composites.
