HS-113 Modified Aromatic Amine Epoxy Curing Agent

Product overview

Engineered for its duty

HS-113 is our workhorse aromatic amine curing agent for high-build epoxy flooring and electrical potting. The modified aromatic backbone delivers a fast-curing, tightly crosslinked network with a high glass-transition temperature (Tg), which translates directly into floor systems that resist indentation, chemical attack and heavy traffic from the very first days of service.

Because the cured network is highly dense and hydrophobic, HS-113 films maintain their properties in wet processing areas, plating lines and battery/energy environments where water, dilute acids and alkalis are constantly present. In electronics, the same chemistry protects encapsulated modules against moisture ingress and thermal cycling.

Key benefits

Why formulators specify it

• Fast cure development
  Shortens project turnaround on flooring jobs and speeds up demoulding of potted assemblies.
• High glass-transition temperature
  Cured films stay hard and dimensionally stable at elevated service temperatures.
• Excellent water resistance
  Suitable for wet areas, immersion-grade coatings and humid climates.
• Superior acid & alkali resistance
  Withstands dilute acids, alkalis and salts typical of industrial floors.
• High hardness with impact tolerance
  Resists indentation and mechanical abuse without brittle failure.

Applications

Where it is used

• Epoxy floor screeds and mortar systems
• Mid coats and base coats of industrial epoxy flooring
• Electronic potting and encapsulation compounds
• Chemical-resistant wall and floor coatings in wet processing areas

Typical properties

Handling & safety

Application and storage

Application

Apply at substrate and ambient temperatures between 5 °C and 35 °C with relative humidity below 85%. Ensure good ventilation during mixing and application.

Pre-test a small sample against your resin batch and project conditions before full-scale use; adjust the mix ratio according to the epoxy equivalent weight of the resin used.

Storage

Store sealed in the original container in a cool, dry, well-ventilated area away from sources of ignition. Shelf life: 12 months from date of delivery when stored correctly.

Packaging

20 kg and 200 kg net steel drums. Other packaging formats can be discussed for project volumes.

Safety

Amine products may cause skin sensitisation. Wear chemical-resistant gloves and eye protection. In case of skin contact, wash immediately with plenty of soap and water. Keep out of reach of unauthorised personnel.
