- Product Applications
- Cardolite NC-558 is usable in high solids or solvent free surface tolerant marine, industrial maintenance, protective, and floor coatings.
- Good chemical resistance and suitability for contact with potable water (Dependent on country regulations) make this curing agent especially acceptable for concrete or metal tank linings and pipe coatings.
- It can be used for coating applications under cold and humid conditions, even over damp and poorly prepared surfaces.
- This product’s fast cure and good hardness make it ideal for applications requiring fast return to service.
- Its ability to cure over a wide temperature range and non-critical mix ratio can bring coatings broad application latitude.

Storage & Handling
- Shelf Life
- 6 months
- Storage Condition
Cardolite products may absorb moisture and carbon dioxide when left in open containers, which could result in increased viscosity, discoloration, reduction of reactivity, and/or crystallization of the products. These products should be kept tightly sealed in their original containers when not in use, and stored in a cool, dry place.
