Alkaline Hot Degreasing

Alkaline hot degreasing is a chemical surface preparation process used to remove oils, greases, machining fluids, dust, and other organic contaminants from metal surfaces. The success of subsequent surface coating processes largely depends on this stage. Insufficiently cleaned surfaces may result in poor coating quality, reduced adhesion, and inadequate corrosion resistance.

The combination of alkaline chemicals and surfactants effectively removes oils and contaminants from the metal surface. As a standard pre-treatment process before zinc plating, phosphating, and galvanizing, alkaline hot degreasing prepares components for subsequent coating operations. Performed using specially formulated alkaline chemicals at controlled temperatures, this process ensures optimum surface cleanliness, allowing zinc plating, phosphating, and other surface treatments to achieve more uniform, durable, and long-lasting results. At Çinkosan, alkaline hot degreasing is carried out using both immersion and spray processes. Throughout production, bath concentration, operating temperature, and process time are continuously monitored to ensure optimum surface cleanliness for every component.
