HDI Waterborne WanHua 268

HDI Waterborne WanHua 268

 

Product Description：

Aquolin 268 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 adhesive. After addition of Aquolin 268, the ready-to-use mixture must be used within the pot life.

Aquolin 268 can be diluted with the solvents, such as propylene glycol methyl ether acetate (PMA), propylene glycol diacetate (PGDA), butyl acetate, etc. Only PU grade solvents (< 0.05% water) should be used and the solvents must be tested in advance by the user to determine suitability.

Properties：

  1. High gloss and high building up.

  2. Excellent weather resistance.

*These properties are typical but do not constitute specifications.

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 once the package is open.

Logistics and Handling

Storage Conditions:

– Storage in original sealed Covestro container.

– Recommended storage temperature: 0 – 30 °C.

– Protect from moisture, heat and foreign material.

General information: Hydrophilic isocyanates are very moisture-sensitive and react with water to form carbon dioxide and insoluble ureas. The containers must always be kept tightly closed. The accessof water in all forms (moist air, solvents, moist containers) must be prevented, because the generation of carbon dioxide can lead todangerous increases in pressure. Storage at higher temperatures will result in increase of color and viscosity.
