Plastify
Plasticizing with Duracoat
What is plastification?
In plastification, we coat the metal surface with a relatively thick and pore-free plastic layer. The thick barrier of at least 250 microns protects the metal surface from various external aggressive influences. Especially in outdoor applications, plasticized metal guarantees long-term protection with minimal maintenance.
The plasticizing process
We apply thermoplastic (Abcite® or Rilsan®) or thermosetting powders (Resicoat®) to a preheated metal surface via swirl sintering or hot spraying. The powder particles then melt into the rough contact surface and form a smooth and pore-free plastic layer.
How does vertebral sintering work?
Preheated pieces are immersed in a swirl sinter bath. That is filled with thermoplastic coating powder. Through a swirling air circulation, the powder particles reach all corners and edges of the object to be plasticized to fuse with it immediately upon contact. A safe and fast technique for plasticizing metal.
How does hot spraying work?
Thermoplastic powder particles are sprayed onto the metal and immediately melt into the metal surface. Unlike powder coating, in this technique the metal is first raised to a high temperature. The dimensions of the metal pieces are not limited to those of the vertebral sinter bath, and there are more choices in terms of color finish.
The possibilities and limitations
- Layer thicknesses from 250 to 2000 microns
- 5 ovens for object dimensions up to 7800 x 2400 x 1900 mm and maximum 3000 kg
- Mechanical pretreatment via manual or machine grit or corundum irradiation

Fluorinated coatings
Duracoat has a wide range of options in surface treatment techniques and therefore also in printing. As a final finish, we can also print or print on your coated products or painted parts. V coat provides a total solution through various in-house printing techniques.
Powder coating
Powder coatings are environmentally friendly and stand for scratch-resistant results. Powder coating applies to all kinds of ferrous metals. V coat does it all with a structural focus on quality.
Pretreatment
The quality of powder or wet-lacquer coating stands or falls with proper and thorough pre-treatment of the materials. Only then will you get an even, scratch-resistant and beautiful end result.
Abcite® coating
For corrosion protection and chemical resistance, Abcite® is recommended. As well as for extreme corrosion protection in water treatment in the marine and offshore sector.
Additional Services
Duracoat also offers the solution for additional services. One of the sister companies within the group, V coat, specializes in printing, assembly and EMI shielding.
