High Build, or 1,2 - 1,4 mil film build materials are popular in many electrocoat applications today due to their ability to provide smooth, corrosion resistant films without the use of a primier surfacer. Results of salt spray, scab corrosion, and ship corrosion experiments indicate that equivalent protection can be provided using a new intermediate build or 0,8-1,0 mil film build electrocoat primer. When subtituted for a high build primer, this intermediate build primer represents a substantial reduction in material usage (and therefore cost) to the end user. A comparison of the abilities of the new intermediate film build electrocoat primer and some standard high build electrocoat primers to fill metal finishing marks on test panels and on production auto parts will be shown. Ra, Rz, and R3z surface parameter measurements for the two types of electrocoat primers will be described. For each surface parameter R, the filling factor or (Rsubstrate-Rpaint)/(Rsubs trate) will be shown for each type of electrocoat paint. The data show that the new intermediate film build electrocoat primer can provide filling properties equal to or better than a high build electrocoat primer
