Epodur 1890 weld thru primer is a ready-to-use weldable coating. Apply to metal surfaces in order to provide a rust proof surface and maintain quality welds. This coating offers increased heat resistance, reduced porosity and pin-holing as compared to traditional weld-able coatings. Epodur 1890 is a versatile primer easily applied to improve weld efficiency preventing the formation of corrosion that forms between welded substrates especially during prolonged storage periods.
