Cardolite NC-540 is a unique type of epoxy resin hardener known as a phenalkamine.
The distinctive structure of phenalkamines imparts a unique combination of desirable properties to the curing agents and the coatings, adhesives, and castings derived from them.
Phenalkamines exhibit rapid cure, even at low temperatures with a workable pot-life and the ability to resist moisture while curing, making them ideal for all season cure, surface tolerant coatings.
Phenalkamines are accepted for use in coatings for potable water contact in several countries.
Cardanol is a unique natural phenolic material obtained by distilling CNSL and serves as the primary building block for Cardolite curing agents.
The molecule is composed of an aromatic ring with an OH group and a long aliphatic side chain, which bring valuable intrinsic benefits to coating materials.
From the beginning, Cardolite products have been based on cashew nutshell liquid, a natural, non-food chain, and annually renewable biomaterial.
The technology has been widely adopted because there are inherent performance benefits gained from using this starting raw material without sacrificing performance or cost.
The relatively low viscosity of Cardolite products brings good workability to formulations as coatings trend towards higher solids and solvent free systems for the protection of applicators and the environment.

Cardolite phenalkamide technology is a new category of epoxy curing agent that fills a gap between polyamide and phenalkamine technology.
By chemically combining the two technologies, phenalkamide curing agents offer the benefits of both while mitigating their limitations.
Phenalkamide technology can be used in many applications where polyamide technology currently prevails to bring a new level of performance, reliability, application latitude, and cost savings.
General protective coatings, for example, that require good color stability and long overcoatability can avoid having separate summer and winter versions by using a phenalkamide based converter package.
The overall system will have fast cure, low temperature cure, and excellent corrosion protection without the need for tertiary amines or anticorrosive pigments.
A single formula's broader application latitude gives coating manufacturers protection from summer converter packages being used erroneously in low temperature conditions, and simplifies finished product and raw material inventory management.
Cardolite offers epoxy curing agents of various chemistries to meet the requirements of a broad range of applications.
Our offering includes phenalkamines and phenalkamides both derived from CNSL as well as polyamides and modified cycloaliphatic amines.
Coatings formulators will find good options for industrial, marine and protective, transportation and flooring applications.
Adhesives formulators will also encounter solutions for structural, building and construction, automotive and electronic systems.
In addition, some of our low viscosity, solvent-free epoxy curing agents are excellent choices for composite applications looking to incorporate bio-content.
Moreover, many of our curing agents are suitable for specialty applications such as electronics, and potable water and food contact.
