Cardolite® NX - 2021

1 of 30 products in this brand
Cardolite® NX - 2021 is a low viscosity multipurpose resin modifier and accelerator designed for coatings, adhesives, and other applications. Its long hydrophobic aliphatic side chain provides excellent early water resistance and corrosion protection. It enhances workability, increases solids content, and accelerates cure without sacrificing performance properties.

Functions: Rheology Modifier, Thinner

End Uses: Solventless & High Solids Coating

Compatible Polymers & Resins: Epoxies (EP)

Labeling Claims: Bio-based, From Renewable Resources, Non-Toxic, Solvent-free

Product Applications
  • Cardolite NX-2021 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, chemical resistance, and gloss are not significantly compromised with the addition of NX-2021.
  • 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.

Acceleration Effect

Cardolite® NX - 2021 - Acceleration Effect - 1

Cardanol grades do not reduce gel time as much as Nonyl phenol.

Impact Resistance

Cardolite® NX - 2021 - Impact Resistance - 1

Cardanol grades improve impact resistance of epoxy systems due to long aliphatic side chain. Improvement is more significant than for Nonyl phenol.

Storage & Handling

Shelf Life
12 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.
