In the few car has just come out of the years, primer is used, alkyd phenolic or epoxy ester primer. The alkyd resin or epoxy ester iron red primer is most widely used. These two kinds of primer with excellent comprehensive mechanical properties, most has been dominated by industrial primer paint market.

The data show that the mechanical properties of conventional alkyd iron red primer are very good, but the matching of the salt fog resistance, and finish (a tremendous contrast, often exists between its iron red primer and car commonly used color cannot form the best coverage) and so are unable to meet the automotive industry is becoming more and more demanding of coatings industry demand.
