Aquolin 269 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 and adhesives. After addition of Aquolin 269, the ready-to-use mixture must be used within the pot life.

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.
Packaging:
200KG/drum Please fasten the packaging cover as soon as possible after original packaging to prevent the mixing of other substances such as moisture and other substances that may affect the performance of the product.
