Curtain coating is the method of applying paint or varnish to wood products such as sheet materials, where a high application is required (> 100 gr / m2).
The coating is pumped from a can and pushed through a curtain head, after which the coating falls down on the workpiece as a curtain. The curtain head is placed between two conveyor belts, where the coating is collected and returned to the can when no workpiece is being fed through.
Because there is no pulverization there is no coating loss.
The curtain head is adjustable in height and placed on a separate withdrawable frame unit provided with a solvent tank in which the curtain head can be placed after use in order to minimize cleaning.
Soest has all the techniques, ranging from simple to automated machine setups. We would like to invite you to the Soest test center to jointly come up with the best solution for your product.
Curtain coating machine model VG
The VG models are available in different widths, from 300 to 1300 mm.
Inclined curtain coating model SG
The model SG has the possibility to incline the conveyor belt up to 30 degrees. With just one feed, the flat part and one side of the product can now be coated simultaneously. This machine is therefore extremely suitable for coating, for example, panels where the flat surface together with the sides have to be coated.
The machine is limited to a working width of 300 mm (flat part + 1 side) and in horizontal position (flat part only) 350 mm.
Spray-curtain coating combination model SGC
This machine is a combination of two techniques, namely spraying and curtain coating together.
The machine has a spray booth with on both sides an automatic spray gun to provide both sides of the workpiece with a coating. The flat part of the workpiece is then provided with a coating by curtain.
Curtain coating does not have any loss of coating and therefore does not require filters and extraction. This saves a huge saving of coating and cleaning, making this combination technique ideal for, for example, panels where the flat surface together with the sides have to be coated.
