High temperature paint which can withstand high temperature oxidation and corrosion medium. High temperature coating industry in general in 100℃-1800℃, most of high temperature paint use the high temperature solution, paint requirements in the environment can achieve stable physical properties (no shedding, no bubble, no crack, no powder, no rust, allow a slight discoloration). General selection of silver or black, the two color is relatively stable, not easy to fade at high temperature. Titanium dioxide has excellent thermal stability, temperature resistant 350-400℃ not change color and 600℃ variable to tan, up to 1200℃ to 1300℃ it becomes irreversible dark brown.
Heat resistance of zinc oxide in white pigment is 250 to 300℃, lithopone is suitable for long-term heat at 250℃.
In the black pigment, long-term heat applied to carbon black at 250℃, if the temperature is above 300℃, the color will fade. The long-term heat resistance of graphite powder and manganese dioxide for 300℃.
The red pigment in red iron oxide and cadmium red for 250℃when long-term heat.
Yellow, yellow and yellow cadmium strontium long-term high temperature can only withstand 200℃.
