  A compound of formula (I) having advantageous properties when used as a latent curing agent for compositions containing isocyanate groups, and to compositions containing the compound of formula (I). The compound of formula (I) is odourless, is liquid and has comparatively low viscosity at room temperature and is stable in storage together with isocyanates. It makes possible odourless single-component polyurethane compositions which have good stability in storage, do not produce bubbles when cured in the presence of moisture, and cause no problematic odour emissions, giving a cured elastic material having good mechanical properties, good heat stability, a surprisingly non-adhesive surface and little tendency towards plasticizer migration.

  具有优越特性的化合物，其化学式为（I），在含异氰酸基团的组合物中作为潜在固化剂使用时具有优势，并且包含化合物（I）的组合物。化合物的化学式（I）无味，液态，在室温下粘度相对较低，在与异氰酸酯一起储存时稳定。它使得可能制备无味的单组分聚氨酯组合物，在储存中具有良好稳定性，在存在湿气时固化时不产生气泡，并且不会产生有问题的气味排放，从而获得具有良好机械性能、良好热稳定性、惊人的非粘附表面和少量塑化剂迁移倾向的固化弹性材料。
