- Phenalkamines are a distinct range of natural epoxy curing agents that provide very fast cure, even at low temperatures (<40 °F or 5 °C), with a good workable pot life.they have excellent resistance to moisture during cure, and offer good chemical resistance, and flexibility.
- These unique properties make them an excellent choice for marine and offshore coatings, solvent-free industrial floor coatings, railcar and agricultural/construction equipment coatings, portable water coatings, and tank and pipe linings. they are also used for adhesive, automobile, and electrical potting applications.
- Phenalkamines are synthesized from CNSL (Cashew nutshell liquid). this viscous reddish brown coloured liquid is derived from the shell of cashew (Cashew Tree, Anacardium occidentale L).
- Crude CNSL is one of the major sources of naturally occurring non-isoprenoid phenolic lipids such as anacardic acids, cardols, cardanols, methylcardols and polymeric materials. Royce International Corp. and Cardolite Corporation are major manufacturers of Phenalkamine Curing Agents.
