How Smartvacuum improves several aspects of the basecoat application process

Verniciatura fondo pannelli piani

Applying a basecoat to a flat panel is usually performed using one of the following techniques: roller coating, spray coating or curtain coating. Each system has specific advantages depending on a number of factors. Introducing an innovative application technique using vacuum technology adds a new set of opportunities and benefits for manufacturers of cabinet doors, panels and bathroom furniture.

Any wood or wood-based flat panel can be coated using vacuum application technology, especially those with rounded edges.

A closer look at vacuum application technology

Easily used to process flat rounded doors, J-pull versions and panels with ABS edges, Smartvacuum applies 100% UV acrylic paint in a single pass without the application head coming into physical contact with the substrate. Between 100 and 140 g/sqm are deposited in an extremely clean, homogeneous manner avoiding any product build-up on any parts of the panel. The process is simple, clean, eco-friendly and cost-efficient.

Flash-off is performed after basecoat application and prior to the panel completing its drying in a UV-R oven.

Which benefits does Smartvacuum add to the coating process?

Using a 100% solid UV product, this makes it a relatively sustainable process and the coating is more stable over time compared to polyurethane or polyester-based products, also requiring a shorter drying time. One benefit which distinguishes the use of vacuum application techniques regards the matching between panel surface and edge.

Smartvacuum is the perfect partner for Smartedge

They use the same technique and the same lacquer. That makes it simple to achieve the best junction seam between the flat surface and the edge of the panel. Softer to the touch than what can be achieved using other techniques, the quality of the finish on panels with rounded edges is improved and fewer operations are required to obtain the perfect finish.

A complementary solution to other application techniques

Vacuum application boasts several advantages over other coating technologies, but there is no need to consider it an alternative. To appreciate the benefits, we need to consider the current techniques.

Roller coating lines

Roller coating lines include:

  • substrate sanding
  • application of basecoat for adhesion
  • three base coat applications with single and double coaters and intermediate gelling
  • final drying
  • base coat sanding followed by finishing

Curtain coating lines

Curtain coating lines include:

  • substrate sanding
  • basecoat application
  • UV gelling 
  • UV base coat application with curtain coater and special flash-off tunnel
  • drying
  • base coat sanding followed by finishing

Spray coating lines

Spray coating lines are a closed-circuit solution applying polyurethane or polyester-based basecoats in multiple steps on flat surfaces and edges. This is followed by lengthy drying times since the panels must be stabilised at suitable intervals in the warehouse before the sanding and finishing processes.

Comparing the benefits of vacuum application technology

Starting from the eco-friendliness of 100% UV acrylic paints, there are a host of benefits which will reduce consumables, costs, lead times, handling requirements and the need for space.

  • no need to round off corners after drying and before sanding
  • fewer machines required, so less cleaning and lower consumption
  • lower sanding costs and less waste
  • shorter lead times, production flexibility
  • smaller footprint, more space in the factory
  • fewer process stages resulting in fewer panel handling requirements
  • clean edge at machine inlet vs. curtain coating

Implementing Smartvacuum, the coating line would look like this:

  • panel sanding
  • basecoat application and gelling
  • application of 100-140 g/sqm of 100% UV product in a single pass
  • flash-off for 5/6 minutes
  • UV oven drying
  • sanding or matt/glossy finish, if required, performed using another coating technique


The Smartvacuum technology, associated with the Smartedge range for edge finishing, makes the process simpler, faster, ecological and cost-efficient, eliminating many manual operations.

Frequently Asked Questions






这项技术有很多优势。 首先,传输效率达到惊人的99%。 真空涂装机体积小,因此占用的工厂空间很小。,使用真空涂装机,可一站完成360°砂光,型材涂装和漆膜固化,使生产效率得以优化。 没有空喷漆雾,不对环境造成任何污染。 漆膜厚度高,以玻璃棉面板为例,漆膜厚度可达700 µm。


对漆膜质量的评判带有很强的主观性。 但是,如果产品对漆膜硬度要求较高,那么该技术通过使用固体含量为80%的涂料,可以实现较高的漆膜厚度(例如,天花板可达到700 g / m2),并同时减少干燥段费用。即使是较复杂的型材,稳定的漆膜厚度也是真空涂装技术在质量方面的关键优势。。


这将取决于你是使用紫外线固化涂料还是水性涂料。使用UV涂料,真空涂装机每道油漆涂布量为25至75µm(1至3 mills),而使用水性涂料,真空涂装机每道油漆涂布量为25至150µm(1至6 mills)。您还需要考虑电能消耗和压缩空气消耗。


最小长度为915 mm(36“),最大宽度为305 mm(12”)。这个范围之内的任何尺寸都可以。
