Aquolin® 278

Aquolin® 278 is a water dispersible polyisocyanate based on hexamethylene diisocyanate(HDI). In combination with waterborne polyurethane, polyacrylate, etc., it can be used for water-borne coatings. Thanks to its low viscosity and ease of hand- mixing, Aquolin 278 can be used to prepare “solvent-free hardener” in order to produce ultralow VOC coatings. After addition of Aquolin 278, the ready-to-use mixture must be used within the pot life.

Storage & Handling

Storage Conditions
  • The product should be stored in dry conditions above 5°C and below 35°C with the integrity of the packaging, and prevent direct sunlight.
  • The validity of this product is for 12 months, performance assessment is recommended before use after shelf life.
  • The product should be protected from freezing during storage.
  • Water dispersible polyisocyanates are very moisture-sensitive and react with water to form carbon dioxide and insoluble ureas.
  • The generation of carbon dioxide can lead to dangerous increases in pressure.
  • The containers must always be kept tightly closed and the access of water in all forms must be prevented.
  • It is suggested to use up once the package is open.
