In order to achieve flawless, high-gloss lacquer surfaces, surface specialist Oltrogge from Bielefeld offers polyester spraying systems for precious wood and carbon fiber coating. The coating of precious wood or carbon fibers is used in numerous application areas, especially for products in the luxury segment. These include interior elements for automotive accessories in the premium and luxury vehicle sector as well as aircraft interiors. It also includes yacht and shipbuilding, the manufacture of high-quality furniture and the production of pianos and grand pianos.
Double diaphragm pump, pressure regulator and polyester spray gun
For a high-gloss surface, the mixture and atomization must be optimally coordinated. In the PSG 8 polyester spraying system from Oltrogge, a double diaphragm pump delivers the polyester lacquer. A pressure regulator controls the dosage. The peroxide hardener is metered and delivered via a special 4-liter tank. Here too, the quantity can be adjusted using a precision pressure regulator. The system is also available as an option in the PSG-8H version with heater. This enables easier application of very viscous material and thus provides an even surface.
Polyester spray gun based on the external mixing principle
The polyester spray gun was developed by Oltrogge itself and works according to the external mixing principle: The peroxide hardener is injected into the atomizing air channel, while the horn air remains without hardener admixture. This ensures maximum availability of the system.
No gloss without sanding
However, even with the best mixing and atomization technology, a high-gloss surface is not created directly with the material application. Instead, it must be sanded several times afterwards. The finished sanded surface is characterized by its durability, UV resistance and longevity. This makes it ideal for applications that have to withstand heavy use or long-term exposure to sunlight, for example.
