Before working with this product, you must read and become familiar with the available information on its risks, proper use, and handling. Information is available in several forms, e.g., in particular in the currently valid safety data sheets and product labels. For further information contact your Covestro representative.
Product description
Hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI). Baymedix® FP520 can be used as a cross-linking agent in polyurethane based aqueous dispersions.
Applications
The handling of materials containing reactive polyisocyanates and residual monomeric HDI requires appropriate protective measures referred to in the safety data sheet. This product may therefore be used only in the intended applications.

Storage
- 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 access of water in all forms (moist air, solvents, moist containers) must be prevented, because the generation ofcarbon dioxide can lead to dangerous increase in pressure. Storage at higher temperatures will result in increase of color and viscosity.
