Dip Coating Processes

DipCoatingJessup Manufacturing wanted to create this blog to introduce to you and to industrial organizations the use of dip coating processes. Dip coating is a specialized industrial coating process that is used in the manufacturing of coated materials. The best example of the use of the dip coating process involves the making of candles, where dip coating is used to create a thin film around the candle that allows the wax to solidify and harden. Once the wax of the candle has solidified, the dip coating can be peeled away, if need be, to reveal the final product solution as it was intended. This method represents the most popular use of the dip coating process – allow a product to harden or mold into its final form, where it then can be used for its intended function. Essentially, dip coating can also be used for flexible and loose substrates as well, keeping the material together to attain its full operational capacity.

The following will explain the stages of the dip coating process:

First, the substrate is immersed into the solution of the coated material, where the speed is maintained at a constant level, otherwise the substrate can become erratic, rendering the immersion faulty. Second, and once the immersion is sustained, the substrate will remain in the solution for an extended period of time until the maximized solution that can be obtained is determined. The substrate will then begin to be pulled up. Third, a thin layer of coating will mold itself to the deposited substrate while the product is being pulled up. The maintaining of speed at which the substrate is withdrawn is as important as maintaining the speed at which it is immersed. Whatever speed is determined, it must be constant, and depending on the speed used, will also determine how thick or thin the coating is on the substrate (faster speed gives a thicker coating, whereas a slower speed leads to a thinner coating).

The final two stages involve drainage, which is the time allotted to allow excess liquid to drain from the surface, and evaporation. The evaporation process involves the solvent slowly evaporating from the liquid, which leads to the forming of a thin layer. If you happen to be using a more volatile solvent, such as alcohol, evaporation begins faster and maintains a rapid rate; meaning evaporation likely began during the deposition and drainage steps.

This blog only lends a glimmer into the process of dip coating, though its intention is to provide enough information to see if this process is something your industrial business could benefit from its implementation. To learn much more about the dip coating process, and whether the process is right for your operations, you should consult with Jessup Manufacturing. Jessup will provide all the necessary information you need to determine if this process is worth your while. If it is, then Jessup can also explain how your business can best benefit from the process.
