- Features
Cured with bisphenol-A or bisphenol-F or phenol novolac based epoxy resins. Ark 172 is most suitable as curing agent for
- Fast drying with adequate pot life
- Combined with the advantages of high hardness, good adhesion and moderate flexibility
- Cured coatings are drying faster and excellent resistance to solvents, inorganic acids and alkalies
- Its 100% reactive and also very low viscosity makes it safer and very convenient to handle
- Low shrinkage, fast attainment of strength, high impact and abrasion, high degree of transparency and gloss
Applications & Uses
- Applications
- Compatible Polymers & Resins
- Coating Type
- Applications
- Most suitable for curing epoxy coating and flooring system.
- Ark 172 is designed with low viscosity and ideal for high solids transparent coatings, chemical resistant mortars and linings. Most suitable for cost effective light color self leveling floorings.
