INTRODUCTION
Amino resins are reported to be the predominant crosslinking agents for thermosetting industrial coatings, and melamine-formaldehyde (MF) resins are the most widely used type of amino resin.[1] MF resins have been used extensively to crosslink hydroxyl-functional acrylic or polyester co-reactants for over 60 years.[2] Other groups that are known to react with MF resins include carboxylic acids, amines, and amides.[2] Recently Blank[3] stated that secondary carbamate groups in urethanes are potentially reactive with MF resins but that no publications have specifically discussed this subject. The purposes of the work reported here are to demonstrate ...
