ABSTRACT:
Epoxy-based nonwoven webs are provided. The webs are formed by meltblowing a blend of an epoxy resin and a polycaprolactone (PCL) polymer. Whereas epoxy resins by themselves produce nonwoven webs which are brittle and glassy, epoxy/PCL blends have been found to produce webs which have good flexibility and elongation and are not glassy. If desired, once formed, the epoxy/PCL webs can be cured with, for example, an epoxy crosslinking agent to produce webs having enhanced solvent resistance properties.
