- Product Applications
- Cardolite NX-2026 was designed as an accelerator and formulation tool to reduce VOC levels and viscosity on coating systems used in heavy duty marine, protective, industrial, and floor coatings.
- Although higher in viscosity than some other modifiers, the structure of this product gives excellent dilution efficiency to help rapidly reduce viscosity for improved pigment wetting, flexibility, and general application properties.
- Coating physical properties such as water resistance, corrosion protection, color stability, chemical resistance, and gloss are not significantly compromised with the addition of NX-2026.
- This product can be added to either component of an epoxy system to provide good cure acceleration and replace or reduce levels of hazardous accelerators like nonylphenol.

- Cardanol, NX-2026, showed increased flexibility compared to Nonyl Phenol.
- Addition of Cardanol improves bond strength.
- Nonyl Phenol shows less impact on mechanical properties than Cardanol.

Technical Details & Test Data
- Dilution Curve
- Dilution Power Graph
- Both cardanol grades show much better dilution power than Decoupage MNP.
- NCO Blocking Agent Technology
High purity and light color cardanol, NX-2026, is an effective isocyanate blocking agent that can be used to replace petro-based phenols. NX-2026 blocked NCO systems should be lower in viscosity and require lower deblocking temperatures than phenol. Moreover, cardanol can act as a flexibilizer in the final matrix.

- Environmental burden is bigger for NX-2026 due to additional processing steps required to achieve higher purity.
- Acceleration Effect
- MNP shows fastest acceleration based on gel time, but both cardanol grades still provide good acceleration.
- Viscosity Profile
- Viscosity Advancement with D.E.R. 331
- NX-2026 shows the best stability with Epon 828. Better choice than UL 2023 for part A.
Storage & Handling
- 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.
