    Curtain coating systems in the industry

    Curtain coating systems for precise industrial surfaces

    Curtain coating systems enable the economical coating of profiles, panels and components with low-viscosity media. At Venjakob, we develop robust systems that combine stable coating patterns, clear process control and high system availability. The technology is suitable for protection and coating tasks in various branches of industry.

    Advantages of curtain coating systems

    To ensure that coating processes are stable and efficient, precise media guidance and optimised system parameters play a decisive role. Curtain coating systems enable precisely these controlled conditions and thus ensure reproducible results even with demanding geometries.

    Optimised media routing

    The defined guidance of the coating medium reduces turbulence and ensures a controlled flow pattern in the flood area.

    Constant process conditions

    Temperature, viscosity and flow rate can be precisely adjusted so that production batches can be run reproducibly.

    Efficient recirculation systems

    Recoverable media flows reduce consumption and operating costs - ideal for series production with high throughput volumes.

    Stable coating with varying geometries

    The system compensates for changing profile shapes and ensures uniform wetting, even with more complex component edges.

    Low maintenance effort

    Cleaning-optimised assemblies facilitate the handling of low-viscosity coating media.

    Waterproofing and impregnation with curtain coating systems

    Hydrophobic coatings reliably protect components against moisture and the effects of the weather. Curtain coating systems wet workpieces completely so that coating materials penetrate deeply and create a lasting protective effect. The technology is particularly suitable for façade profiles and construction elements with functional surface requirements.

    "For hydrophobic systems, a calm, completely encircling flow is crucial. This is exactly what the curtain coating reliably achieves." - Christian Streit, Business Unit Manager Wood | Furniture

    Glaze application and priming with curtain coating systems

    For decorative glazes and low-viscosity primers, curtain coating offers a homogeneous coating pattern. The defined wetting improves the adhesion of subsequent coating layers and ensures a harmonious surface appearance for wood and panel workpieces. The controllable media quantity means that colour tones remain stable and reproducible over longer production runs.

    Our VEN FLOW curtain coating systems

    Solutions for all your workpieces

    With VEN FLOW, we realise flexibly configurable curtain coating systems for hydrophobic, decorative or preparatory coating tasks. The systems work in a continuous flow, enable efficiently guided media flows and support stable results with changing component geometries.

    Hydrophobisation of profiles, panels and façade elements

    VEN FLOW enables the hydrophobisation of components on all sides using curtain coating. The system protects surfaces from moisture and the effects of the weather, works in an overflow process and is designed for high throughput.

    Glaze application on profiles, panels and building elements

    VEN FLOW is suitable for the even application of glazes and thin-layer coatings. The processes ensures harmonious colour effects and stable coating results for profile parts and panels.

    Priming of components in preparation for subsequent coating

    With VEN FLOW, low-viscosity primers can be applied reliably. The even wetting improves the adhesion of subsequent coating layers and reduces the absorbency of the substrate.

    Frequently asked questions about curtain coating systems

    These answers summarise typical questions relating to curtain coating systems and impregnation systems in a compact format. They will help you to assess which applications and materials are suitable for curtain coating. We will be happy to advise you personally on project-specific requirements.

    A curtain coating system describes the technical processes of overflowing in a continuous flow. An impregnation system describes the application purpose of protection or hydrophobisation. VEN FLOW fulfils both requirements.

    The workpiece is completely wetted with hydrophobic media. The coating material penetrates and creates a protective effect. With VEN FLOW, this takes place in a continuous flow.

    Curtain coating systems are particularly suitable for profiles, panels and construction elements made of wood and wood-based materials. Depending on the medium, other substrates are also possible.

    If components are exposed to moisture or weathering, the curtain coating achieves a reliable protective effect through complete wetting.
