General galvanizing (HDG)

Explore Chemical Solutions for Hot-Dip Galvanizing and General Galvanizing

Hot-dip galvanizing (HDG) is one of the most effective methods for protecting steel against corrosion currently available. To ensure the quality of the coating, enhance aesthetics, and extend product lifespan, selecting appropriate surface treatment chemicals and additives is crucial.

General galvanizing is particularly effective in providing a long-lasting protective layer for steel against harsh environmental conditions.

With over 40 years of experience in metal surface treatment, AD Chemicals offers a comprehensive portfolio of chemical products for the hot-dip galvanizing industry, including post-galvanizing passivation solutions, pre-painting chemicals in the DUPLEX system, process optimization additives, and specialized paint strippers.

These solutions were developed to meet the stringent technical requirements of modern industry, while also aligning with sustainable and environmentally friendly production trends.

Chemical Passivation After Hot-Dip Galvanizing (Post-Galvanizing Passivation)

Following the hot-dip galvanizing process, the steel surface requires passivation treatment to enhance corrosion resistance and improve surface quality. AD Chemicals offers chromium (VI)-free passivation solutions that can be used directly in the cooling bath or evaporation bath.

The solution forms a uniform protective film on the surface of galvanized steel, enhancing the durability and aesthetics of the product.

Outstanding advantages

Contains no chromium (VI), environmentally friendly.
Increases the corrosion resistance of galvanized steel surfaces.
It can be used directly in cooling tanks or chillers.
An economical solution that helps optimize operating costs.
It can be adjusted to suit different surface types and technological conditions.
Meets international standards such as Qualisteelcoat and GSB .

Pre-Treatment Chemicals for Painting in the DUPLEX System

For galvanized steel products requiring coating, the pre-treatment process plays a crucial role in improving paint adhesion and enhancing corrosion protection.

AD Chemicals provides specialized pretreatment solutions for the DUPLEX system, helping to:

Increases the adhesion of the paint coating.
Enhance the durability of the paint system.
Improved overall corrosion resistance.
Meets international technical requirements and quality standards.

Additives for Optimizing Hot-Dip Galvanizing Processes

In addition to surface treatment solutions, AD Chemicals also offers a wide range of specialized additives to improve operational efficiency and extend system lifespan.

Degreasers

Degreasing products help remove grease and impurities from the steel surface before processing, creating optimal conditions for a high-quality plating layer.

Pickling and Cleaning Additives

These additives help to increase cleaning efficiency, removing oxide layers and deposits from metal surfaces, thereby improving the quality of the plating.

Bath Stabilizing Inhibitors

This product group helps:

Extend the lifespan of the treatment tank.
