Last time, we analyzed the factors affecting the quality of the primer paint, and today we are talking about the very important factors affecting the quality of the facade paint. In fact, there are several factors that affect the primer and topcoat. The effect of the primer is generally on the color and adhesion, so the topcoat is very susceptible to the reflective effect.
1. The dry condition of the paint layer has a very important influence on the reflective effect of the façade reflective paint. If the lacquer layer is dry well, it will have a bonus effect on the reflection, but if the surface of the lacquer layer is dried too fast, or the thinner The volatilization is faster, which causes the paint layer to wrinkle, which not only affects the reflective effect, but even makes the facade reflective paint not reflective.
2. Glossiness, before we specifically talked about the gloss problem of reflective paint, the gloss is higher, the reflection effect is better; on the contrary, it may appear non-reflective.
3. Adhesion, this is the same as the primer. If the adhesion of the topcoat is poor, it will affect the service life of the entire facade reflective paint, because once the topcoat is peeled off, the paint layer loses its reflective function and will Ordinary paint is no different.
4. Weather resistance, which is equivalent to the basic elements of façade reflective paint. Poor weather resistance means that the possibility of “survival” in the outdoor is very low, and the service life will be greatly reduced. This is also an important indicator to distinguish the quality of façade reflective paint.
