pretreatment
We have two continuous lines designed to guarantee a high-quiality finish on every piece:
-
Immersion pretreatment with zinc phosphate-based technology.
-
Spray pretreatment with zirconium-based nanoceramic technology.
To obtain an optimal surface before applying paint and allow for:
-
Improved adhesion: eliminates impurities for uniform bonding.
-
Corrosion prevention: creates a protective barrier against external agents.
-
Greater durability: improves resistance to impacts, humidity and UV rays.
-
Improved appearance: prevents defects such as stains or peeling.
-
Compliance with standards: ensures processes aligned with quality standaeds such as ISO, ASTM and CQI-12
application
During powder coating, the coating is deposited onto a pre-treated surface using techniques that take advantage of the powder´s electrostatic charge.
Spray guns are used to generate a powder mist with air. This powder mist with air. This powder adheres to workpiece, covering it evenly.
To achieve a good result, various parameters and techniques are adjusted depending on the type of workpiece being coated.
Curing
Curing in powder coating is the final and essential stage of the process, where the coating becomes a continous, hard, and resistant film.
It consists of heating the coated part to a controlled temperature for a specific time. The powder transitions from a solid state to a viscous gel and, finally, becomes a solid film. This process is typically carried out at a temperature between 160°C and 220°C (the temperatura of the metal) for 10 to 15 minutes.
Once cooled, the film acquires its final properties: color, impact resistance, scratch resistance, corrosion resistance, texture, and others.
