Cataphoresis (KTL) is our standard for surface protection. This extensively proven automotive system ensures uniform coverage, excellent adhesion, and corrosion protection to maximize the durability of every cabin and component.
Cataphoresis, or KTL (Kataforesis Tauchlackierung), is an electrochemical process that applies an epoxy-based primer uniformly to metal parts. The components are immersed in a water-based solution and subjected to an electric field, which causes the coating particles to bond evenly to the surface — even in hard-to-reach areas. The result is a consistent, durable, and corrosion-resistant finish ideal for demanding environments.
Our cataphoresis line follows strict internal quality protocols and is aligned with the most demanding standards of the automotive and industrial machinery sectors. Every batch is tested for coating thickness, adhesion, corrosion resistance, and finish consistency to ensure optimal performance in real-world conditions.
At Mansilla Cabs, we have a fully automated cataphoresis (KTL) line, equipped for high-precision industrial coatings. The system is designed to treat components of varying sizes and geometries, ensuring controlled thickness, repeatable quality, and an efficient process for both short runs and high-volume production.
Furthermore, we integrate post-treatments such as powder coating and custom finishes, completing a value chain focused on durable, high-performance products.
At Mansilla Cabs, we use a multi-stage cataphoresis (e-coat) process to protect every metal cab and component we manufacture. This surface treatment is vital to our cab manufacturing process, ensuring long-term corrosion resistance and uniform coating for all operator cabs and structural parts.
The process begins with a rigorous pretreatment phase, including degreasing, descaling, and a series of rinses to remove oils, oxides, and residues. We apply a tricationic microcrystalline phosphating treatment—one of the most advanced in the industry. This stage uses zinc, nickel, and manganese to create a strong, fine-grain phosphate layer that enhances adhesion and durability.
After thorough rinsing with demineralized water to remove any residual salts, the parts are immersed in a cataphoresis tank. A low-voltage electric current causes positively charged epoxy paint particles to bond to the negatively charged metal surface. This ensures full coverage, even in recessed or complex areas, making it ideal for industrial cabins and high-performance cab components.
The parts are then cured in a convection oven, locking in the coating and providing a tough, chemically resistant finish. This process is compatible with additional powder coatings and meets the highest automotive and industrial standards.
