Epoxy Curing Agents

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 every low viscosity, solvent free epoxy curing agents are excellent choices for composite applications looking to incorporate biocontent. Moreover, many of our curing agents are suitable for specialty applications such as electronics, and potable water and food contact.

Please use the selection chart on this page to find the best curing agents for your application.

Low viscosity, Solvent-free phenalkamines for Marine and Protective Coatings

Cardolite offers many low viscosity curing agents for solvent free epoxy primers and coatings. As examples, NX-5594 and LITE 2002 are excellent options to deliver fast cure even in heavily diluted systems, with the former being ideal for low temperature applications. They both provide long term corrosion protection on surfaces exposed to harsh conditions and show very good re-coatability and mechanical properties.

PHENALKAMINE EPOXY CURING AGENTS

Our phenalkamines are made through a Mannich reaction using cardanol as starting material. They provide very fast cure even below zero temperatures and excellent adhesion and corrosion protection even on immersed surfaces. Similarly, in adhesive applications, phenalkamines deliver very fast bond strength development to various substrates under strenuous conditions of cold temperatures and wet environments (even under water). Additionally, phenalkamines can be applied in a wide range of conditions and show good adhesion even to non-prepared surfaces, lowering application risk failures.

Moreover, through our Ultra LITE proprietary technology, very light color phenalkamines have been developed. The long chain of cardanol in the backbone of phenalkamine epoxy curing agents provides low viscosity and enables solvent free and very high solids coatings. In addition, use levels are non-critical and formulation friendly with 2:1 and 1:1 pack ratios possible.

Phenalkamines are an excellent option for coatings, adhesives, and composite applications.

Phenalkamides protect assets in industrial environments and can be applied in all seasons

PHENALKAMIDE EPOXY CURING AGENTS

Cardolite phenalkamides offer epoxy systems excellent corrosion protection and fast cure while maintaining long pot life, good flexibility and UV resistance, and extended overcoat window. In adhesives, phenalkamides can be used to develop high strength epoxy systems that require high mechanical properties and good thermal resistance. Both coatings and adhesives can benefit from phenalkamides ability to bond well to various substrates such as concrete, blasted and smooth metals, composites and some plastics.

The balance properties of phenalkamides allows for universal use in coating and adhesive applications during all four seasons of the year. DTM coatings are also possible with phenalkamides for higher efficiency. Some grades are drop-in alternatives to commercial polyamides to allow for easy substitution in formulations. High solids and solvent free grades are also available to enable low VOC and low viscosity epoxy systems that cannot be achieved with polyamide chemistry.

Waterborne curing agent technology from Cardolite enables low VOC epoxy coatings with excellent performance

WATERBORNE TECHNOLOGY

The NX-8000 Series waterborne line of curing agents enables zero and low V.O.C. epoxy coatings with solvent-like performance. Cardolite offers a variety of grades that meet the needs of flooring, industrial, container, transportation and protective coatings applications. Building and construction adhesives can also benefit from this technology.

In our offering, formulators will find grades that can protect and bond to various surfaces including challenging substrates such as galvanized steel and aluminum. In addition to excellent corrosion protection, our grades provide wide curing conditions and excellent compatibility with various epoxy dispersion resins. As examples, compatibility with liquid epoxy resin and fast cure even at 10°C and 80% RH can be achieved with NX-8101. Very long pot life and fast recoatability are made possible with NX-8401. Good UV resistance and quick wet-on-wet systems are delivered by NX-8501.

Cardolite also offers water soluble curing agents diluted in 1-methoxy-2-propanol and other solvents upon request, for use in waterborne zinc rich primers or other water-based applications.
