Advanced surface protection for demanding environments
At Addit, we apply Halar® (ECTFE) fluoropolymer coatings designed to protect components operating in contact with aggressive chemicals, corrosive media, high humidity, and demanding environmental conditions.
We support our customers from the earliest stages of product development. We analyze the base material, component geometry, operating environment, and performance requirements to assess the suitability of Halar® coatings and develop a stable manufacturing process. Particular attention is paid to edges, welds, hard-to-access areas, and other locations where achieving the required coating thickness and continuity is most challenging.
A Controlled Multi-Layer Process
The application of Halar® differs significantly from conventional powder coating. After appropriate surface preparation, the component is heated to approximately 300°C.
The coating is then built up gradually as a multi-layer system. Achieving a final thickness of approximately 600 to 1,000 μm typically requires 6 to 12 application cycles. Since the final coating thickness cannot be fully verified before complete curing, the process is controlled through established technological parameters and the experience of our specialists.
Careful control of each application cycle is particularly important for products with complex geometries. Corners, edges, welds, internal cavities, and hard-to-reach surfaces require an individual approach to ensure the required coating thickness and complete continuity of the protective layer.
Addit's Technological Capabilities
The process is carried out in a dedicated installation capable of drying and curing products at temperatures of up to approximately 300°C.
Our facility can process components measuring up to:
- 5000 × 3000 × 3000 mm
- 500 kg
This enables us to apply Halar® coatings to both small components and large enclosures, structural frames, and industrial fabrications.
Halar® coating is delivered as part of comprehensive manufacturing projects. We combine precision sheet metal fabrication, welding, CNC machining, surface preparation, coating application, and mechanical, electrical, and electronic assembly within a single manufacturing process.
As a result, customers can entrust a single partner with the production and protection of individual components or complete modules. This approach minimizes the risk of surface damage during transportation between suppliers and eliminates issues arising from divided process responsibility.
We also support customers in process development, production trials, and the transition from prototypes to stable and repeatable serial production.
Quality Control and Coating Integrity
For Halar® coatings, quality control focuses primarily on the parameters that determine the effectiveness of the protective system: coating thickness, continuity, and integrity.
After the coating process is completed, we verify coating thickness and inspect the continuity of the protective layer, paying particular attention to welds, edges, corners, and complex geometries.
Depending on project requirements, we also perform high-voltage holiday testing to detect microscopic pores and coating discontinuities that cannot be identified through standard visual inspection.
Testing parameters are selected according to the coating thickness and project requirements while complying with applicable standards, including PN-EN ISO 29601, ASTM D5162, and NACE RP0188.
This comprehensive inspection process confirms that the coating meets all technical requirements before the product proceeds to assembly or enters service.
Contact Us
Send us your technical documentation or 3D model together with information about the intended operating environment.
We will analyze the component geometry, material, performance requirements, and the feasibility of applying a continuous Halar® coating, then develop a manufacturing process tailored to prototype, low-volume, or serial production.
