5 Gardner – Holdt Viscosity (in 40% Butyl Carbitol solution @ 25°C) Unmodified Bisphenol-F based Epoxy Resins Bisphenol-F based Epotec® Epoxy Resins have advantage over their counterparts based on Bisphenol-A owing to their lower melt viscosity. This helps in getting films with better leveling and reduced orange peel effect. Chemical resistance of these grades are also better than their respective equivalents on Bisphenol-A.
