Amivion PKA-5020 is a cardanol-modified self-emulsifying epoxy curing agent designed for waterborne epoxy coating systems. The product is based on a cardanol-amine adduct technology, where the long aliphatic side chain of cardanol is incorporated into the curing agent structure to impart hydrophobicity, flexibility, and improved water resistance to the cured coating film. Amivion PKA-5020 is capable of emulsifying standard liquid epoxy resins in water without the need for external emulsifiers, simplifying waterborne epoxy formulation. It is primarily used in corrosion-resistant coatings, industrial floor systems, and metal surface protection applications where low VOC content and environmental compliance are required.
Key Features
- Self-Emulsifying Capability: Amivion PKA-5020 is formulated to emulsify standard bisphenol A liquid epoxy resins directly in water without external surfactants or emulsifiers. This simplifies the formulation process and reduces the number of raw materials required in waterborne epoxy paint production.
- Enhanced Water and Corrosion Resistance: The cardanol-derived long alkyl chain incorporated into the curing agent molecule shields the hydrophilic segments of the cured network, improving the hydrophobicity and barrier properties of the coating film. This contributes to improved water resistance and corrosion protection performance compared to conventional waterborne amine hardeners.
- Low VOC and Environmental Compliance: As a waterborne curing agent, Amivion PKA-5020 supports the formulation of low-VOC epoxy coatings that meet increasingly stringent environmental and regulatory requirements. It enables coatings manufacturers to reduce solvent use without sacrificing coating performance.
- Ambient Cure Capability: Amivion PKA-5020 cures standard epoxy resins under ambient conditions, making it suitable for field application in industrial maintenance, infrastructure protection, and on-site construction coatings where elevated-temperature post-cure is not practical.
- Good Adhesion and Flexibility: The phenolic hydroxyl group in the cardanol structure contributes to strong adhesion to metal and mineral substrates. The long alkyl chain provides a degree of flexibility to the cured film, supporting use in coatings exposed to mechanical stress or substrate movement.
Typical Applications
Amivion PKA-5020 is used as the curing agent component in two-part waterborne epoxy coating systems for industrial and architectural applications. Key end uses include anticorrosion primers and topcoats for steel structures, bridges, and marine infrastructure, industrial floor coatings, and protective linings for chemical storage equipment. Its self-emulsifying character enables direct mixing with commercial liquid epoxy resins to produce stable aqueous dispersions suitable for spray, roller, or brush application.
Additional applications include waterborne epoxy coatings for concrete and cementitious substrates, container and tank interior linings, and maintenance coatings for industrial facilities. The product is also used in the formulation of waterborne epoxy adhesives and primers for metal and composite substrates where low solvent emission is required.
