HDI Waterborne WanHua 278

HDI Waterborne WanHua 278

Product Description：

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 handmixing, 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.

Properties：

Matting effect.
Excellent water dispersibility.
Excellent weather resistance.

Storage：

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 oncethe package is open.
