Abstract

By using bauxite and zircon powder as refractory materials

bentonite of natrium and CMC as compound defloculant and sol silicate

PVB and phenolic resin as compound binding agent

based on the orthogonal testing

the water-based coating for EPC steel castings was developed. The various properties of the prepared coating were examined

and it was compared with coating from the Asland company at the U.S.A in performances. The results show that the prepared coating has the advantages of desirable performance and low cost.
