POLYURETHANE-BASED PRESSURE SENSITIVE ADHESIVES AND METHODS OF MANUFACTURE

摘要

Polyurethane-based pressure sensitive adhesives comprising the reaction product of : an isocyanate-reactive component comprising at least two isocyanate-reactive materials, an isocyanate-functional component; a reactive emulsifying compound; a chain capping agent and an optional chain extending agent. The adhesives, which are preferably pressure sensitive adhesives, can be prepared from 100% solids, waterborne or solventborne systems.
