[Surface Treatment VA Proposal] Black Geomet for Electrodeposition Cation | Development Proposal Case Study
There are many opportunities to consider alternatives to cationics! Let me introduce the benefits of geomat treatment.
The cathodic electrodeposition treatment has issues such as poor electrodeposition painting and adhesion due to slag, decreased corrosion resistance of film damage from flying stones, aging deterioration of electrodeposition, and poor compatibility. With our Geomet treatment, these issues with cationic processes can be resolved. Depending on the product shape, it is possible to achieve value-added (VA) from "ZAM (galvanized steel sheet) + cation" to "steel material + Geomet," ensuring heat resistance and corrosion resistance even when exposed to temperatures above 250°C. 【Advantages of Geomet Treatment (Partial)】 ■ A film is formed even on welds and edges. ■ No need to switch to low-slag wire, reducing costs. ■ Improved adhesion of the Geomet film at welds. ■ No processes using phosphoric acid or acids, eliminating the possibility of brittleness. ■ No concerns about breakage. ■ Even if the film is scratched by flying stones, it is less likely to rust. *For more details, please refer to the PDF document or feel free to contact us.

basic information
**Problems with Cationic Coatings** ■ Heat and Corrosion Resistance - Rust at Weld Joints: Poor electrodeposition coating and adhesion due to slag - Rust at Edges: Difficulty in forming a film at edge areas - Internal Corrosion Protection: Difficulty in forming a film on the inner surfaces of bag-shaped structures - Chipping Resistance: Decreased corrosion resistance due to damage from flying stones, etc. - Heat Sensitivity: Coating is destroyed at 200°C, leading to reduced corrosion resistance ■ Brittleness - Zinc Phosphate and Pickling: Risk of fracture due to brittleness ■ Bolt Tightening - Time-dependent Deformation of Electrodeposition: Thick and ultra-thick coatings may deform over time, resulting in decreased bolt axial force - Poor Fit: The thickness of thick and ultra-thick coatings reduces the fit of bolts *For more details, please refer to the PDF document or feel free to contact us.*
