- Features
Cured with bisphenol-A or bisphenol-F or phenol novolac based epoxy resins. AG 140 is most suitable as curing agent for
- Rapid cure at low temperature(down to 5°C)
- Combined with the advantages of polyamides and aliphatic polyamines for non-critical mixing ratios, wide range of pot life and flexibility alongwith good chemical and solvent resistance
- Excellent water and corrosion resistance
- Low viscosity
Applications & Uses
- Applications
- Compatible Polymers & Resins

Storage & Handling
- Shelf Life
- Minimum Six Months
- Storage and Stability
Hardener AG 140 should be stored in a cool dry place at 2 – 40 °C in the sealed container to achieve shelf life of minimum six month. Product can react with moisture and carbon dioxide in the air. This may result in increase viscosity and reduce its activity.
- Handling Precautions
- May be harmful if ingested or absorbed through the skin and can cause sensitization.
- Will cause severe irritation in contact with eye And skin. Wash thoroughly after handling.
- Adequate ventillation is essential.
- Containers should be tightly closed when not in use or during transportation.
- Do not inhale mist or vapors
- It is recommended to use gloves, safety glasses and protective clothing for safe handling.
