Crosslink mechanisms of high-solids alkyd resins in the presence of reactive diluents

摘要

The drying of alkyds was studied using NMR and mass spectrometry empolying model compounds. Crosslinking occurs via oxidation of unsaturated fatty (linoleic) acids in the resin. Hydroperoxides formed as intermediates are degraded to alkoxy and peroxy radicals by cobalt catalyst.
