FEATURES &APPLICATIONS
XYlink E90 is a colorless, low viscosity aliphatic secondary diamine. XYlink E90 has a moderate reactivity due to the secondary amino group and can make the operating process more convenient. It can be used as the only chain extender or mixed with other diamine or diol chain extenders in the preparation of aromatic and aliphatic polyurethane-urea, polyurea with good performance. Its application includes reaction injection molding (RIM), casting elastomers, spray elastomers, coatings, sealants and adhesives, etc. Aliphatic polyurethane-ureas based on XYlink E90 and aliphatic diisocyanate have outstanding color stabilization.
