ARCOL® E-434

ARCOL® E-434 by Covestro is a polyether polyol. It is a 4,800-molecular-weight polyoxypropylene triol specially modified with ethylene oxide. Because it contains a high percentage of primary hydroxyl groups, it has a relatively high rate of reactivity. ARCOL® E-434 is compatible with most polyether polyols and can be blended with other diols, triols and polymer polyols to achieve desirable modifications of product properties. It is used in sealants & is slightly hygroscopic and may absorb water. The shelf life is twelve months after receipt of material by customer.
