The discoloration of epoxy floor is a very common problem in the process of use, but it will seriously affect the appearance quality of epoxy floor. Therefore, when such problems occur, it must be solved timely. As one of the professional epoxy curing agent r&d and manufacturers in Qinghai, Qinghai epoxy floor paint factory will introduce some techniques to prevent the discolouring of epoxy floor:
1. Select resins and pigments from the paint formula as required
The light and heat resistance of individual pigments in coatings are not good, and some epoxy floor resins have poor weather resistance and are prone to yellowing when exposed to light.
2. Metallic pigment should be packaged separately from epoxy floor paint. When metal powder pigments are stored, they are corroded by free acids left in the epoxy floor and turn from black to green.
3. The epoxy floor shall be thoroughly stirred before construction
The densities of several pigments in polychromatic paints are different. During the storage process, heavy pigments sink and light pigments float. If it is not stirred sufficiently during use, it will not match the original color after being applied.
4. Epoxy floor paint with high acid value should not be installed in iron drums
Varnish with a higher acid value tends to react with iron packing barrels. The varnish becomes less transparent and darker in color. When designing paint formulations, care should be taken not to use pigments that will react with resins or additives.
When mixing and coloring epoxy floor coatings, it is strictly prohibited to mix and color two different types of coatings without testing. Some pigments undergo chemical changes and lose their inherent tinting power, resulting in discoloration or discoloration. If the blue or green paint contains iron blue, the color will fade during storage, but the paint exposed to air will gradually recover after application.
