Gardo Etch: Revolutionizing Aluminum Surface Treatment 

Chemetall's Gardo Etch is a next generation etching technology designed to deliver exceptional optical results for aluminum surfaces in anodizing processes. Available as alkaline long-life etch or as acidic matte process this innovative technology ensures a highly matte, fine-grained, and uniform surface. 

The unique properties of Gardo Etch alkaline long-life etch contribute to improved rinsing and drainage, thanks to reduced viscosity, which simplifies the cleaning process and minimizes material retention. Its advanced formulation supports an extended bath lifespan, ensuring efficient and consistent operations over time. By producing minimal foam during the etching process, Gardo Etch enhances bath utilization, enabling higher rack load capacities and improved overall productivity. 

In addition, Gardo Etch reduces material loss by limiting aluminum dissolution and optimizing the use of chemicals, such as significantly lowering the consumption of NaOH. The formulation also minimizes coarse grain effects, often caused by zinc in alloys, resulting in a smoother and more uniform finish. 

Gardo Etch acidic matte surface etch contributes to significantly reduced volume of sludge as well as reduced fluoride and ammonia content with consequent impact on effluent streams, wastewater treatment and disposal.   

Both Gardo Etch advanced technologies not only improve throughput but also contribute to sustainability by reducing chemical usage and environmental impact. With Gardo Etch, Chemetall delivers an innovative technology that combines cutting-edge performance with eco-conscious practices, ensuring optimal surface treatment for aluminum while addressing the challenges of modern industry.
