4026 is a modified polyether amine curing agent with a fast surface dry, very low viscosity and an essentially colourless appearance. It contains no K-54 accelerator, so cured films gain substantially better water and chemical resistance and improved weatherability.
Product overview
4026 was developed for top-coat quality flooring and clear systems where appearance matters. The polyether backbone keeps viscosity low for easy pumping, mixing and self-levelling, while the absence of K-54 (2,4,6-tris(dimethylaminomethyl)phenol) removes the usual weakness of accelerated amine systems: water sensitivity and yellowing.
Formaldehyde-release concerns are also addressed — free formaldehyde content is minimised, making 4026 a more environmentally responsible choice for indoor flooring, adhesive and potting applications. Finished surfaces show no amine blush, retain high gloss and stay clear over time.

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
Apply at 5 – 35 °C and relative humidity below 85%. Avoid application onto damp substrates to preserve gloss and intercoat adhesion.
Pre-test a small sample against your resin batch and project conditions before full-scale use.
Store sealed in the original container in a cool, dry, well-ventilated area away from ignition sources. Shelf life: 12 months.
20 kg and 200 kg net steel drums.
Amine products may cause skin sensitisation. Avoid contact with skin and eyes; wash exposed skin immediately with plenty of water.
