Solubility/Dilution
Generally, this product has good compatibility with organic solvents such as esters, ether esters, xylene and solvent naphtha 100. But solubility and compatibility must be tested each time. Polyurethane grade solvents (less than 0.05% water) should be used.
Features/Applications
Since Bayhydur® XP 2547 is hydrophilic, it is easy to emulsify in the water phase and is mainly used as a cross-linking agent for water-based hydroxyl polyol binders (Bayhydrol®). Bayhydur® XP 2547 can also be added to traditional hydroxyl-free dispersions to improve their various properties.
Save
This product is moisture sensitive. When stored properly in airtight containers at not exceeding 30°C, this product has a shelf life of at least 6 months. Viscosity may increase slightly over time.
Security: Hazard Identification
Contains isocyanates, which may cause allergic reactions by skin contact. The Product Safety Data Sheet (492659) should be strictly followed. It includes relevant information such as labeling, transportation and storage, as well as relevant information on product use, product safety and ecology.
