Reasons for the discoloration of epoxy floors

1. The difference in pigment density causes the density to sink and increase, resulting in the stratification of pigments.
2. The residual free acid erodes the metallic powder pigments, causing the pigments to turn blackish green.
3. The acid value of the varnish undergoes a chemical change with the stored iron drums, making the color darker.
4. The material's aging resistance is not good, and it will turn yellow when exposed to the sun.
5. The paint itself undergoes a qualitative change, reducing the inherent tinting strength, resulting in fading or discoloration.

Solutions to deal with the discoloration of epoxy floors

1. Sufficient. The coatings are well mixed.
2. Metal pigments and varnishes must be stored independently.
3. Do not use iron drums to hold highly acidic coatings.
4. Resins and pigments should be selected according to requirements. For example, exterior wall coatings should choose those with better light and temperature resistance.
5. Do not select pigments that can undergo chemical reactions with resins or main agents. Experiments should be conducted before the two pigments are mixed and applied.
