Curtain coating solutions

Curtain coating is performed using systems known as curtain coaters. Usually a curtain coater is provided as an end-of-line finishing machine and plays a key role in high quality finishing - to achieve any desired effect: glossy, semi-glossy and matt in different colours.

What is curtain coating?

Curtain coaters are based on the ability of liquid lacquers to form a uniform coat as they fall on items, allowing the lacquer to transfer onto a product surface as the product being processed is fed on. A curtain coater is suitable for application on flat or slightly raised surfaces of any type and on any substrate.

Curtain coaters can be equipped with gravity or pressure heads depending on the paint products to be applied. A system of conveyor belts in and out of the head leads each panel through the coating curtain - ensuring homogeneous lacquer application.


Advantages of curtain coating

The curtain coating technology allows for excellent finishing quality thanks to the homogeneity of the coat of paint on substrates that are generally flat, and the considerable paint weight applied in a single pass. 

It is a versatile technique which can be used with virtually any type of paint, achieving a glossy, semi-glossy or matt finish. Flexible and capable of reaching high output levels, curtain coaters can be integrated into lines as a last finishing step, but are also suitable for basecoat application depending on the type of material to be treated.

Among the advantages:


A curtain coater can become the highest output machine of all, with speeds ranging between 60 and 100m/min.

Technology suitable for all types of paint, water-based, polyurethane and UV, clear or pigmented.

Paints containing aluminium dioxide, corundum or glass microspheres can be applied with this technique to achieve high surface abrasion strength.

Where can curtain coating be used?

Curtain coating can be used for surface finishing of different materials and in a number of industries including:

Frequently Asked Questions

Frequently Asked Questions

01 Which materials are suitable for curtain coating?
Curtain coating is suitable for all materials such as wood and wood derivatives, glass, cork, plastic materials, fibre cement, leather, cardboard, metal, etc. Curtain coaters work panels with flat or slightly raised surfaces.
02 Who are the main users of curtain coating technologies?
Curtain coating is based on a highly effective technology, mainly used by manufacturers of flat cabinet doors, parquet manufacturers, manufacturers of panels of various materials and door manufacturers.
03 What are the advantages of curtain coating?
Curtain coating is one of the best performing technologies in terms of finish quality. It also ensures remarkable advantages in terms of both flexibility and productivity. In curtain coating, all types of paint in the whole available colour range can be used.
04 What types of coating products are best suited for curtain coating?
All types of paint can be used for curtain coating: water-based, polyurethane and UV, clear or pigmented, matt, semi-gloss or glossy paints.

To date, the most commonly used types as both primers and finishes applied with curtain coaters are high quality polyurethane paints and UV paints. For parquet coating, paints containing aluminium dioxide, corundum or glass microspheres can be applied, to achieve high surface abrasion strength.
05 What do I need besides the curtain coater to complete my line?
A curtain coater is a machine that is added to a finishing line as the last coating machine, although in very specific cases, it can be used for primer application. Like in all coating lines, depending on the types of material to be processed, conveyors, sanding machines, brushing machines for cleaning purposes and drying ovens (based on different technology depending on the type of coating product used) are also needed.
06 What is the degree of flexibility of curtain coating machines?
Curtain coaters are highly flexible, both in terms of product quantity to be applied, and in terms of application options and different positioning along the coating line.
