Acm Sign Material

3.Use pure water for cleaning after washing. Pure water is alsocalled deionized water, which guarantees coating quality.

4.Conduct invert film treatment process after pure water cleaning. Invert film treatment can improve wet ability of organic coating so as
to increase special surface area, which improves aluminum panel anticorrosion property and coating adhesive property. It adopts mixed coating method in this process to ensure that invert film uniformly adheres to both upper and lower surface of aluminum panel acm sign material. Invert film shall not be too thick or too thin. Both may affect coating adhesive force.

5 .Conduct drying procedure after invert film treatment. Controldrying temperature to ensure that aluminum panel surface temperature is under 100°C. If the temperature is too high, crystalwater of the invert film will decompose and cracks and micropores on surface acm sign material  will increase, which will directly affect aluminum panelanticorrosion property and increase surface roughness. This is infavor of coating adhesive force, i.e. increasing coating adhesive force.

6  Cool it after drying and drive it for inspection. If qualified, wrap itup as formation final product.
