Aluminium Pretreatment BMG-063.5

Special chemical solution for aluminium surface preparation prior to electroplating


Short Description

The Aluminium Pretreatment BMG-063.5 is a chemical solution designed for the effective, current-free preparation of aluminium surfaces before subsequent electroplating processes.
Aluminium rapidly forms a stable oxide layer when exposed to air, which prevents proper adhesion of electroplated coatings. This pretreatment removes oxide and passive layers, activates the surface, and improves wettability, ensuring reliable adhesion of later metal coatings such as nickel, copper, or gold.


Applications

The aluminium pretreatment is used for:

  • Removal of oxide and passive layers on aluminium

  • Surface activation prior to electroplating

  • Improved adhesion of subsequent metal coatings

  • Preparation for tank, brush, or pen plating

  • Ensuring uniform, durable electroplated layers

Proper pretreatment is essential for achieving high-quality and long-lasting coatings on aluminium.


How the Pretreatment Works (Simple Explanation)

Aluminium naturally reacts with oxygen and forms a thin but dense oxide film that blocks electroplating. The Aluminium Pretreatment BMG-063.5 uses a chemical activation process to prepare the surface:

  1. Cleaning: Aluminium parts are cleaned and degreased.

  2. Pretreatment: Parts are immersed in the aluminium pretreatment solution.

  3. Activation: The chemical reaction removes oxides and activates the surface.

  4. Rinsing: Parts are thoroughly rinsed with water.

  5. Plating: The activated surface is now ready for electroplating.


Advantages of Aluminium Pretreatment BMG-063.5

  • Effective oxide and passive layer removal

  • Improves adhesion of electroplated coatings

  • Current-free process, easy to apply

  • Suitable for various aluminium alloys

  • Compatible with multiple subsequent plating systems

  • Improves coating quality and durability

Safety Information

Chemical pretreatment solutions contain active substances and must be handled carefully:

  • Wear chemical-resistant gloves, safety goggles, and protective clothing

  • Avoid skin and eye contact

  • Rinse immediately with plenty of water in case of contact

  • Use only in well-ventilated areas

  • Do not ingest; keep out of reach of children

  • Do not eat, drink, or smoke while handling

  • Dispose of according to local chemical waste regulations


Conclusion

The Aluminium Pretreatment BMG-063.5 is an essential process step for successful electroplating on aluminium.
By effectively removing oxide layers and activating the surface, it ensures excellent adhesion, uniform coatings, and long-term durability of subsequent electroplated layers. This product is suitable for hobby users, workshops, and professional electroplating operations seeking reliable and repeatable results.
