MULTRANOL® 3900 by Covestro is a 4800-molecular-weight polyoxypropylene triol specially modified with ethylene oxide. It is a clear viscous liquid and is slightly hygroscopic and may absorb water. The terminal end-groups have a high percentage of primary hydroxyl end-groups, giving it a relatively high rate of reactivity with isocyanates. MULTRANOL® 3900 is compatible with most polyether polyols and can be blended with other diols, triols, and polymer polyols to achieve desirable modifications of product properties.
