Powder coating

Integral part of our company is powder coating.

Powder coating is a process of the powder application by creating of the electric field between the powder and coated part. Due to the different polarity the powder is attracted to the surface of the part where sticks and makes compact layer. The layer is further hardened at temperature 160-190°C. The powder melts and makes coating of 60-200 microns.

We are ale to coat the parts having the maximal dimensions 120 x 115 x 80 cm and the parts which have to fit in to the imaginary block having the dimesions: 155 x 80 x 160 cm

Used kinds of powder coating materials:

  • epoxipolyester (for indoor use parts)
  • epoxid (for indoor use parts, more oils and petrol-proof)
  • polyester (for outdoor use parts; industrial UV-proof)
  • polyuretan (outdoor paint, UV and chemicals-proof)

The most significant benefits:

  • manual application of the powder – it is possible to coat the shapes and faces, which are un-reachible for the automatic lines
  • enviroment friendly (no toxic and volatile solvents)
  • reaching of the coating thickness of 60 – 200 microns during one operation
  • great anti-corrosion and anti-abrasion character of the material

It is needed to make some pre-treatments in order to secure the required coating adhesion.

We use the barrelling, shot blasting, anodizing (in cooperation), degreasing or phosphating in our company.

Control processes after the powder coating:

  • Thermal verification during the hardening: Testo 925
  • Colour characters: Color reader CR10
  • Inspection of the coating thickness: MINITEST 3100
  • Coating adhesion: set for performing of the chipping test according to ČSN EN ISO 2409.
