Dip Pre-Treatment is an essential process that prepares the surface of metal for painting and coating by cleaning, degreasing, and removing surface contamination or other impurities.

But what exactly is dip pre-treatment and why is it so crucial?

Dip pre-treatment is a process that is typically used on metals that will be painted or coated. It cleans the metal and removes any contaminants so that the paint or coating will adhere better. This is especially important on metals.

If the metal is not prepped properly, the paint or coating will not adhere to the substrate meaning that overall performance will be compromised.  Dip pre-treatment is a necessary step in order to achieve a flawless finish.


What is Dip Pre-Treatment Cleaning?

Pre-treatment is a critical step in the metal finishing process. It provides the necessary foundation for subsequent processes by removing contaminants, promoting adhesion, and improving paint appearance and durability.

Dip pre-treatment cleaning is conducted prior to the application of a liquid paint or powder coating. The purpose of this cleaning step is to remove contaminants that could potentially hinder the adhesion of the coating. This includes dirt, dust, grease, oil, and other residues.

Dip pre-treatment is typically conducted using an overhead handling system that is designed to move a basket of components through various stages of the chemical pretreatment.  The components dwell in a chemical stage for a specified time before being rinsed off with pure water, this process continues until each stage is complete.  The components are then dried before the paint finish is applied.


Why is Dip Pre-Treatment Conducted?

Dip pre-treatment is conducted for a variety of reasons. The most common reason is to prepare the surface of the metal for painting or powder coating. This process provides better adhesion and helps to prevent rust and corrosion. Other reasons for dip pre-treatment include:

  • To remove contaminants such as dirt, grease, or oil
  • To etch the surface of the metal to provide better paint coverage
  • To improve the overall appearance of the finished product


The Dip Pre-Treatment Process…

Pre-treatment is a critical step in the metal finishing process. It ensures that the surface is clean and free of contaminants before the finishing process begins. Dip pre-treatment systems are specially designed to clean and prepare metal surfaces for finishes such as painting, plating, or powder coating.

Dip pre-treatment systems typically use a series of tanks filled with different chemicals and water rinse stages. The metal object is dipped into each tank in succession, allowing the chemicals to react with the surface of the metal.

This process removes oils, greases, and other contaminants from the surface of the metal, preparing it for the next step in the finishing process.

Dip pre-treatment systems are an essential part of any metal finishing operation. By thoroughly cleaning and preparing the surface of the metal beforehand, you can ensure that your final finish will be flawless.
