Described are reactive fusion adhesives made from liquid polyether and/or polyester polyols and aromatic diols with at least one diisocyanate. Such adhesives have a very low fusion viscosity and a high initial strength. They are particularly suitable for use in bonding poorly thermally conducting adherends such as foams and non-wovens as well as adherends which are sensitive to heat.
L'invention concerne des colles réactives à fusion à base de polyols polyéther liquides et/ou de polyols polyester et de diols aromatiques avec au moins un diisocyanate, qui ont une très faible viscosité à la fusion et une très grande résistance initiale. Ces colles s'utilisent tout particulièrement pour coller des substrats à mauvaise conductibilité thermique tels que des mousses et des matériaux non tissés, ainsi que des substrats sensibles à la chaleur.
