What are the requirements for ambient humidity for anti-collision reflective paint?
Sep 10, 2018

Many manufacturers often emphasize "three-point paint, seven-point work" with customers, which is enough to see how important construction is for anti-collision wall reflective paint. In the previous article, Xiaobian and everyone talked about the relevant requirements for the ambient temperature during the construction of reflective paint. Today, Xiaobian should continue to analyze the construction of the anti-collision wall with the environmental humidity requirements. Humidity also refers to the relative humidity of the atmosphere. Under certain atmospheric temperature conditions, the amount of water vapor contained in the air is quantified. The relative temperature is usually expressed in a percentage manner.

When performing anti-collision wall reflective paint construction, the relative humidity is preferably below 85%. Generally, under this humidity condition, the surface of the substrate is not prone to condensation, and the quality of the coating can be guaranteed. When the relative humidity of the environment exceeds 85%, if the temperature drops slightly, the temperature of the surface of the substrate will decrease accordingly, which is slightly lower than the normal temperature, and the surface of the substrate will also produce condensation. In this case, The construction quality of the reflective paint will have a corresponding impact. Therefore, it is necessary to test the relative humidity of the environment during construction. If the humidity is too low or too high, it is not suitable for the construction of the anti-collision wall reflective paint.
