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.
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 paint coats and ensures a harmonious surface appearance for wood and panel workpieces. The controllable media quantity means that color tones remain stable and reproducible over longer production runs.
What is the difference between curtain coating systems and impregnation systems?
A curtain coating system describes the technical process of overflowing in a continuous flow. An impregnation system describes the application purpose of protection or hydrophobization. VEN FLOW fulfills both requirements.
How does an impregnation system for wood and profiles work?
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.
Which materials are curtain coating systems suitable for?
Curtain coating systems are particularly suitable for profiles, panels and building elements made of wood and wood-based materials. Depending on the medium, other substrates are also possible.
When does hydrophobization with curtain coating systems make sense?
If components are exposed to moisture or weathering, the curtain coating achieves a reliable protective effect through complete wetting.
