Guide
Powder coating is a dry finishing process in which finely ground coating powder is electrostatically applied to a grounded component. The charged powder is attracted to the surface and remains in place until the component enters the curing oven. During curing, the powder melts, flows and chemically cross-links into a continuous, durable coating that adheres strongly to the properly treated surface.
Electrostatic application
The electrostatic charge attracts the powder to the grounded component, helping the applicator achieve efficient and controlled coverage. Complex shapes, deep recesses and difficult geometries may require additional application techniques to achieve consistent coverage.
Benefits
Powder coating alone does not prevent corrosion. Substrate condition, chemical pretreatment, coating selection and correct curing all contribute to performance.
Preparation
Surface preparation is the overall process of ensuring that a component is in a suitable condition for coating. It may include inspecting the substrate, identifying rust, oil, old coatings, residues or other contamination, and deciding whether additional cleaning or stripping is required before the standard chemical treatment process.
Chemical pretreatment is a standard part of Talaween’s powder-coating process for virtually all components. It cleans and conditions the substrate before powder application and is essential for supporting reliable adhesion, corrosion resistance and long-term coating performance.
Without proper treatment, the powder may initially appear acceptable but cannot be relied upon to bond and perform correctly over time. For this reason, chemical pretreatment is included in Talaween’s normal powder-coating process rather than being presented as an optional upgrade.
Step by step
Step 1
The material, dimensions, quantity, existing condition, intended use, colour, finish and required delivery schedule are reviewed.
Step 2
If the component has significant rust, old coatings, oxidation or difficult contamination, an additional cleaning or stripping service may be recommended and quoted separately. Laser cleaning is one possible option but is not a mandatory stage in standard powder coating.
Step 3
Virtually all components proceed through Talaween’s standard chemical treatment process to clean and condition the substrate and support proper powder adhesion and corrosion resistance.
Step 4
The treated component is dried and prepared for powder application. Masking, plugging or specialised hanging arrangements may be used where required by the component.
Step 5
The selected powder is electrostatically applied to the grounded component using controlled spray techniques.
Step 6
The component is heated according to the requirements of the selected powder system. During this stage, the powder melts, flows and chemically cross-links into the finished coating.
Step 7
The completed component is visually inspected for coverage, appearance and consistency. Talaween also measures cured film thickness before components leave the operation.
Step 8
The finished components are prepared for collection or delivery according to the project arrangement.
A durable powder-coated finish starts long before powder is sprayed. Substrate condition, chemical pretreatment, powder selection, application, curing and final inspection all contribute to the quality of the finished coating.
