| 摘要 |
<p>This invention relates to a thermosetting primer composition having a low VOC content useful in the manufacture of automobiles and trucks in which the film-forming binder comprises a thermal polymerization initiator and an addition-polymerizable ethylenically unsaturated monomer which serves a dual function of solvent and binder polymer formed in situ on thermal curing to deliver low VOC and desired rheological and physical properties. These primers are especially useful in reducing emissions, while also meeting today's performance requirements, such as ease of application and excellent physical properties such as corrosion resistance, a high level of adhesion to primed and unprimed substrates, and provide a surface to which conventional automotive topcoats will adhere.</p> |
