D-325K
D-325K Phenalkamine Modified Epoxy Curing Agent
D-325K is a phenalkamine-type modified epoxy curing agent combining very fast cure at low temperatures with outstanding adhesion. Its phenolic structure gives cured films excellent toughness and corrosion protection, and the product can be tinted to match project colour schemes.

Product overview
Engineered for its duty
Built on a phenalkamine backbone, D-325K is designed for contractors who cannot wait for warm weather. It develops through-cure reliably at low ambient temperatures, keeps its fast reactivity in thick screeds, and bonds aggressively to concrete, steel and primed substrates.
The aromatic phenolic segments give the cured network a rare combination of flexibility and chemical resistance: films flex with substrate movement instead of cracking, while maintaining the barrier properties required for anti-corrosion primers and industrial flooring in aggressive environments.
Key benefits
Why formulators specify it
- Fast cure at low temperature
Reliable cure development even in cool conditions and winter construction windows. - Excellent adhesion
Bonds strongly to concrete, steel, primers and aged coatings after surface preparation. - Tintable formulation
Can be pigmented or tinted for coloured screeds and coatings. - Tough, flexible films
Phenolic structure delivers crack resistance and mechanical durability. - Superior anti-corrosion performance
Ideal for primers and mid coats on steel and reinforced structures.
Applications
Where it is used
- Epoxy floor screeds, mid coats and base coats
- Civil engineering and stone casting works
- Electronic potting adhesives
- Anti-corrosion primers for steel and concrete structures

Values shown are typical, determined under standard laboratory conditions, and are provided for guidance only. They do not constitute a specification. Please test a small sample against your resin system and application conditions before bulk use. The most current Technical Data Sheet is available on request via our contact form.
Handling & safety
Application and storage
Application
Mix only with clean, dry tools. Apply at 5 – 35 °C where possible; below 10 °C allow longer induction and cure times.
Pre-test a small sample against your resin batch and project conditions before full-scale use.
Storage
Store sealed in the original container in a cool, dry, well-ventilated place away from ignition sources. Shelf life: 12 months. Store away from light with the container closed; gradual darkening of colour during long storage is normal and does not affect performance.
Packaging
20 kg and 200 kg net steel drums.
Safety
As an amine product, D-325K may cause skin sensitisation. If the product contacts skin, wash immediately with large amounts of water and seek medical advice if irritation persists.
