Cardanol Based Technologies Phenalkamines are obtained from CASHEW NUT SHELL LIQUID (CNSL), which is a renewable natural resource. CNSL is a monohydroxy. Phenol having a long hydrocarbon Chain, the meta position. The unique properties of CNSL are used to develop Phenaldamines. Phenalkamines (curing agents) based on cardanol have unique advantages over some traditional chemistries. The different grades vary in the viscosity, molecular weight, amine value, and solid content. These products are manufactured to extracting specifications, are used to diverse applications, including coating (Protective, Marine, Floor, Industrial), adhesives and laminates, low temperature curing agents, low VOC, corrosion protection and high performance in adverse environmental conditions. Phenalkamines are a class of curing agents that exhibits outstanding performance in epoxy systems, Phenalkamines provide excellent corrosion protection and adhesion, great mechanical and chemical properties and fast cure at low temperatures; excellent thermal shock resistance, construction, transportation, industrial paint manufacturers and electronics adhesive formulators can take advantage of these properties for a better formula.
What we produce Phenalkamines are a distinct range of natural epoxy curing agents that provide a speedy cure, even at low temperatures (<40 F or 5 C), with a great 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 pine linings. They are also used for adhesive, automobile, and electrical potting applications. Phenalkamine Adducts are a unique type of epoxy curing agents based on the latest modified phenalkamine technology. These products exhibit extremely rapid cure even at low temperatures with a workable pot life. It allows applications of 2 coats per day at low temperatures as little as 5 C. Adducts will also not give blush formation as the primary amines are partially cross-linked with epoxy resins. Adducts also give more chemical resistance property as these products have more molecular weight than the precursor. Phenalkamides are designed to provide coating formulators with the benefits of both polyamides and phenalkamines in one product. Phenalkamides have the excellent fast curing and corrosion protection properties of phenalkamines, but with improved flexibility, overcoat window, and color stability that are typical of polyamides. These balanced properties enable the use of one workhorse curing agent for multiple applications in marine, offshore, protective, and industrial coatings.

Phenalkamine Curing Agent It is a Green Technology Product because the source of cardanol is Cashew Nutshell Liquid (CNSL) Oil. The Mannich reaction of cardanol, formaldehyde, and certain amines is called a phenalkamine. Phenalkamines and adducts of phenalkamine share some similar advantages to other Mannich base curing agents, such as extremely fast cure, low-temperature cure (even below 0 C), excellent chemical resistance, good surface appearance, good moisture tolerance, and non-blushing properties. However, due to the long aliphatic side chain of cardanol, phenalkamines also have very good pot life, good flexibility, surface tolerance, and excellent water and saltwater resistance. Advantages over polyamide resin in terms of low-temperature cure even at high humidity. These curing agents have relatively low viscosity and high solid content (Solvent Free System).
Phenalkamine Curing Agent The fast and low-temperature cure properties of phenalkamines have several benefits for coating formulation. Application productivity can be significantly improved, and the ability to apply a coating in low temperatures allows for a longer or even year-round painting season. Faster cure also means protected surfaces can be re-coated or returned to service more rapidly, including solvent-free formulations that will continue to cure when immersed in water and solvent-based coatings that will continue to cure in poorly ventilated conditions. In forced cure industrial coating applications, phenalkamines can help save energy by lowering oven cure temperatures or improving process efficiency via increased production line speeds. Finally, a fast cure can also help protect coating manufacturers from coating failures. By reaching a high level of cross-linking very quickly, coatings develop their stability early and avoid problems when the environmental conditions change after application. The high hydrophibicity of phenalkamines provided by the long linear side chain also brings many benefits to coating formulations compared with some other technologies. Water sensitivity of the phenolic hydroxyl and other formulation components can be counteracted, which reduces the chance the resin binder barrier will be broken and increases corrosion protection. Adhesion to poorly prepared or tough wet surfaces, such as water-saturated concrete, is especially good with phenalkamines because this hydrophobic effect ensures surrounding water does not influences the surface resin bond. Phenalkamine technology, such as innovative solvent-free, low viscosity, and faster-curing products.
