Unmodified bisphenol-F based epoxy resins

The Epotec range of bisphenol-F based epoxy resins have lower melt viscosity than do their counterparts based on bisphenol-A. This helps in getting films with better levelling and a reduced orange peel effect. Besides, the chemical resistance of these grades is also better than their respective equivalents on bisphenol-A.

Aditya Birla Chemicals (Thailand) manufactures the following grades of unmodified bisphenol-F based epoxy resins:

YDF171 | YDF170LV | YDF173 | YDF 172
