Phenalkamine epoxy hardener
Phenalkamine epoxy curing agents are synthesized primarily from cardanol, a key component derived from cashew nut shell liquid, along with other phenolic compounds. These phenols react with aliphatic amines to form a molecular structure that includes aromatic rings, hydroxyl groups, and aliphatic chains, which impart unique performance characteristics.
Phenalkamines are renowned for their ability to cure rapidly at low temperatures and adhere well to various substrates, even under damp or wet conditions. They offer excellent chemical resistance and flexibility, making them suitable for use in demanding environments.
These curing agents are widely applied in marine coatings, protective industrial coatings, and adhesives where fast curing and strong resistance to harsh conditions are essential.
