Curtain Coating Machine

Introduction

Kerone’s Curtain Coating Machines are designed for industries that require ultra-smooth, streak-free coatings at extremely high production speeds. Using a continuous free-falling liquid curtain, this technology delivers highly uniform, glossy, and defect-free coatings over papers, films, foils, and specialty engineered substrates. Curtain coating is especially preferred for multilayer applications and precision surface treatments where consistency, speed, and surface aesthetics are critical.

Coating and impregnation has increased its demand in market over time, Coating is a method of applying a coat of a liquid on a solid material by way of absorption. Coating also used for applying a fine powdered coat on the solid core using a liquid sticker kind of approach. Often the solid material is coated to protect it from the dust, chemical reaction, slightly thickening the material; it also results in the increase in the life of material. Impregnation is also achieved by the similar kind of process that is followed for coating and the equipment used. Impregnation is to convert the liquid into solid granules; it dries out the liquid content the solid granule structure left behind. With a suitable formulation this can be used to deliver a liquid active material that can be released on application. Impregnation is useful for getting a solid granule from a liquid active.

Why Choose Kerone Curtain Coating Machine

We at KERONE design and manufacture various types of coating and impregnation dyers, as the dryer is most critical to achieve best and efficient result hence we take all the precision and design with the care to avail the best possible result in coating and impregnation plant. We design and built solution for various type of coating.
Kerone’s curtain coater systems are engineered with advanced fluid delivery controls, precision curtain stabilization, and optimized flow distribution to ensure a stable, ripple-free, and bubble-free liquid curtain. These machines support both low-viscosity and high-viscosity formulations, allowing operation across a wide range of coating types. Designed for high-volume production, they ensure superior thickness consistency, minimal waste, and long-term process stability, making them ideal for premium surface finishes and multilayer coatings.

Types and Features of Curtain Coating Machine

Kerone offers several curtain coating configurations tailored for diverse industrial coating requirements. Single-layer curtain coaters provide a smooth, uniform application ideal for standard coatings, while multilayer curtain coaters enable simultaneous application of multiple functional layers within a single pass, significantly increasing productivity. High-viscosity curtain systems are designed for thicker or specialty formulations that require controlled curtain stability. Curtain coaters with integrated recirculation systems reduce material waste by continuously collecting and reusing excess coating fluid. Precision edge guide systems ensure clean edges, uniform curtain spread, and defect-free coverage across the entire substrate width. All systems can be fully integrated with automated flow controllers, curtain gap adjustments, and multi-zone drying units to form a complete high-speed production line.
