本文探讨了使用热熔性聚氨酯固化粘合剂的优点。描述了反应性热熔胶的性能，并探讨了选择这种胶粘剂类型的原因。有代表性的最终用途以及分配方法、应用参数和处理注意事项。考察了反应性热熔胶聚氨酯技术的新进展，如汽车用无空隙固化剂、改进的锅稳定性和脂肪族体系。

THIS PAPER EXAMINES THE ADVANTAGES OF USING CURING HOTMELT POLYURETHANES FOR ADHESIVE APPLICATIONS. PROPERTIES OF THE REACTIVE HOTMELTS ARE DESCRIBED AND REASONS FOR SELECTING THIS ADHESIVE TYPE ARE EXPLORED. REPRESENTATIVE END-USES ARE SHOWN ALONG WITH DISPENSING METHODS, APPLICATION PARAMETERS, AND HANDLING CONSIDERATIONS. NEW ADVANCES IN REACTIVE HOTMELT POLYURETHANE TECHNOLOGY ARE EXAMINED, SUCH AS VOID FREE CURES FOR AUTOMOTIVE, IMPROVED POT STABILITY, AND ALIPHATIC-BASED SYSTEMS.
