4. Resins and matrices for anticorrosion applications
4.1 Conventional or unsaturated polyesters
Please refer to
Here, we shall confine ourselves to the technical knowledge needed to evaluate polyesters in terms of their resistance to corrosion and chemicals.
-
Composition
Unsaturated polyesters are obtained by polycondensation of one or more diacids with one or more dialcohols, where at least one of the ethylenically double-bonded components can subsequently react...
