Optimized Surface Cleaning and Corrosion Protection
A properly selected chemical pretreatment removes even microscopic impurities, oils, and machining lubricants from metal surfaces—contaminants that mechanical cleaning cannot always reach. The process forms a thin conversion layer on the metal surface, which significantly improves paint adhesion and prevents corrosion from spreading beneath the paint film.
Chemical formulations and bath concentrations are closely monitored and standardized, ensuring consistent quality for every production batch. All processes meet the strictest industrial quality requirements and environmental standards.

Gardobond Methods
Gardobond X 4739 and Gardobond X 2020, which are currently in use, represent the state of the art in the chemical activation and priming of metal surfaces.
-
Effective Grease Removal
A multi-stage washing and rinsing process thoroughly removes machining and storage greases from even the most complex structures prior to coating.
-
Optimized Corrosion Protection
The chemical treatment creates a microscopic bonding surface that significantly increases the durability of powder coating in demanding climate exposure classes.

Frequently Asked Questions About Chemical Pretreatment
We serve metal, machinery, and equipment manufacturers throughout Finland, offering industrial-scale capacity and uncompromising quality. Below you’ll find answers to the most common questions related to chemical pretreatment.
Even if a metal surface appears clean to the naked eye, it almost always has invisible films of oil and grease left behind by machine tools. If paint is applied directly to such a surface, its adhesion is compromised and the coating may flake off easily. Chemical pretreatment removes these contaminants and chemically alters the metal surface so that the paint adheres to it without cracking.
