Iron oxide red is a more commonly used pigment mainly used in coatings and paints. In the process of using iron oxide red, users understand that the use of the product may be affected by temperature. In fact, the product itself is relatively stable. In the control range, its color will not change, but once the product's operating temperature is exceeded, the temperature will increase as the temperature rises, and the color will become deeper. The overall degree of change will become more and more obvious. Below we will Let's briefly introduce.

1. If the temperature exceeds 100 ℃, the color of iron oxide red will gradually change to dark red.

2, Iron oxide red gradually changes color to red phase over 130 ℃.

3. Products over 300 ℃ will gradually change color to deep red.

4. Iron oxide red gradually changes color to deep red over 400 ℃.

Many people think that in the process of using iron oxide red, it is possible to improve the discoloration by improving the purity of iron oxide red. In fact, it is not advisable. So if we use iron oxide red in the process, if the temperature exceeds the specified problem, In order to avoid affecting the quality of the product, some attention should be paid.
