Abstract
Select metal salts of mono and di aromatic sulfonic acids and aliphatic sulfonic acids are effective latent acid catalysts in coating compositions capable of acid catalyzed crosslinking and provide coating compositions with lower cure temperature and quicker cure times than encountered with conventional sulfonic acid catalysts, have excellent storage stability and avoid drawbacks of epoxy and amine blocked sulfonic acid catalysts.
