General Description
Phenalkamine Hardeners are high-performance epoxy curing agents derived from the reaction of cardanol with polyamines. They are engineered for fast curing, excellent adhesion, and superior chemical resistance, particularly in demanding environments. Supplied as low-viscosity liquids, phenalkamines enable efficient curing even at low temperatures and under high humidity conditions.
These hardeners are widely used in protective coatings, marine applications, flooring systems, and structural adhesives where rapid cure, early water resistance, and long-term durability are critical. Their unique molecular structure delivers a balanced combination of toughness, flexibility, and corrosion protection.
