PVD coatings vs. liquid metal coating
Liquid metal coatings and the wet paint process are an interesting
alternative to PVD coatings for optical refinements.
Liquid metal and PVD coating are processes for refining materials with an additional metallic surface. While PVD coating is mainly used in the fields of production engineering and toolmaking, liquid metal coating offers numerous possibilities for decorative surface design of different substrate materials in addition to its functional purpose.
With both methods, perfect, durable and optically brilliant surfaces can be achieved, the respective technique has its own characteristics and advantages. In the following we will give you an overview of these methods used in the field of industrial painting and surface finishing.
What is PVD coating and what does this process offer?
The abbreviation PVD stands for Physical Vapour Deposition. What does this bulky term mean?
A PVD coating takes place in vacuumized automatic machines. In the vacuum chamber the metallic coating material is put into a vaporous state. The metal particles are transported to the workpiece, where they are deposited and bond with the workpiece surface. The process usually takes several hours.
PVD coating is used in numerous industries from food processing and medical technology to ship restoration. In the automotive sector and in the production of jewellery and spectacles, PVD coating is mainly used to enhance the optical and decorative value of products. However, since the PVD process is very complex and expensive, a coating with metals in a wet paint process is a more cost-effective, alternative solution, especially in these areas.
Liquid metal coating refines all suitable substrates
In the wet paint process, a metallic layer such as copper, bronze, brass, gold, tin, zinc, aluminium, iron, stainless steel is applied. Liquid metal coating is neither an electrochemical nor a baking process, but rather a cold compound is produced with this method. All materials that are suitable for painting are suitable: Plastics, wood, steel and composite panels. Furthermore, mineral workpieces made of granite, sandstone, concrete, plaster, terracotta, fibreglass, etc. can be coated with our painting process. This method creates jointless composites, there is no limitation in terms of shapes and elements.
The wet paint process with paintable metals opens up a wide range of possible applications. Not only as an alternative to PVD coating in automotive interiors or exteriors, in the production of jewellery and eyewear, but also in architecture, interior design and interior decoration, for ceilings, walls, furniture and floors.
Painting with liquid metals, also known under the English term "liquid metal", offers an extended colour spectrum and convinces with a first-class colour quality. The liquid metal coating can be extended by specially developed colour shades, resulting in completely new design surfaces with a brilliance never seen before.
This special form of industrial coating opens up a multitude of new possibilities, especially in the decorative area, in addition to the standard properties.
