After the road yellow black reflective paint is applied, the paint body drops and sags, and the surface of the paint film is uneven, which is called glazing. The six main reasons for this are:
1. Excessive amount of diluent added to the reflective paint causes the paint to be too thin and the adhesion is reduced, causing the reflective paint to sag under the action of gravity;
2. The reflective paint is too thick, and the paint layer is too heavy to cause drooping;
3. The temperature in the construction environment is too low, causing the diluent to be difficult to volatilize and the paint film to dry too slowly;
4. Excessive heavy pigments in the road yellow black reflective paint, so that some of the paint body drops;
5. The surface of the construction substrate is not flat, the thickness of the substrate is not well grasped, the degree of drying is different, and the place where the paint layer is too thick is prone to sag;
6. The surface of the construction substrate was not cleaned, oil and impurities were attached, and the surface of the substrate was not completely dried, resulting in the sag of the road yellow black reflective paint.
