Amivion PKA-5030 is a cardanol-modified self-emulsifying epoxy curing agent formulated for waterborne epoxy coating systems. Drawing on the natural bio-based cardanol structure derived from cashew nut shell liquid, Amivion PKA-5030 integrates a long aliphatic side chain into the amine curing agent backbone, delivering improved hydrophobicity and barrier performance in cured coating films. As a self-emulsifying hardener, Amivion PKA-5030 can emulsify standard bisphenol A epoxy resins directly in water, enabling the production of high-solids, low-VOC two-component waterborne epoxy coatings. It is suited to industrial protective coatings, anticorrosion primers, and infrastructure maintenance applications requiring environmental compliance without compromising film performance.
Key Features
- Self-Emulsifying Waterborne System: Amivion PKA-5030 emulsifies standard liquid epoxy resins in water without external emulsifiers or surfactants, enabling simple two-component waterborne epoxy formulation. The resulting dispersion provides a stable, low-VOC coating system suitable for spray or brush application.
- Cardanol-Derived Hydrophobicity: The pendant long-chain alkyl group from the cardanol component reduces the water permeability of the cured epoxy network, improving resistance to moisture uptake, osmotic blistering, and underfilm corrosion in demanding service environments.
- Ambient and Low-Temperature Cure: Amivion PKA-5030 provides effective curing of epoxy systems at ambient temperatures, making it practical for field application in construction, marine maintenance, and infrastructure protection where controlled curing conditions are unavailable.
- Improved Coating Flexibility: The cardanol side chain introduces a degree of chain mobility into the cross-linked network, contributing to improved impact resistance and flexibility compared to standard rigid amine-cured epoxies. This supports use on substrates subject to mechanical stress or thermal cycling.
- Low VOC and Environmental Compliance: As a waterborne curing agent, Amivion PKA-5030 supports the formulation of low-VOC protective coatings that meet stringent environmental and workplace health regulations, enabling manufacturers to transition from solvent-borne systems without significant performance trade-offs.
Typical Applications
Amivion PKA-5030 is used as the hardener component in two-part waterborne epoxy coatings for metal and concrete substrates in industrial and infrastructure applications. Key uses include anticorrosion primers and intermediate coats for steel structures, bridges, pipelines, and marine vessels; industrial floor and tank lining systems; and maintenance coatings for chemical processing and water treatment facilities. Its self-emulsifying character allows direct combination with commercial liquid epoxy resins to produce ready-to-apply waterborne coating formulations.
Additional applications include waterborne epoxy adhesive primers for structural bonding and surface preparation, protective linings for potable water and industrial storage tanks, and coatings for prefabricated construction elements where rapid ambient cure and low environmental impact are required. The product is also evaluated as a binder component in waterborne epoxy grouts and repair mortars for concrete infrastructure.
