Master Coat®
Powder Coating


Powder coating is a type of dry coating, which is applied as free-flowing dry powder. The coating adheres to the surfaces electrostatically and is then cured under heat to allow the powder to harden and create a compact surface protective layer. In comparison to conventional wet painting, powder coating allows to cover the element more thoroughly, leaving no unpainted spots. 

There are several advantages of powder coating over conventional solvent-based coatings:

  • Apart from the decorative function, powder coating remarkably improves the corrosion resistance, especially on carbon steel zinc plated surfaces
  • Powder coating can produce a much thicker layer than conventional wet painting, without running or sagging
  • After hardening, the coating meets the requirements for color lasting, gloss stability, UV resistance, as well as abrasion and impact resistance
  • Hardened coating stays flexible and can even absorb significant expansion of the supporting surface, as well as its’ bending or twisting
  • Powder coated surfaces generally have fewer appearance differences between horizontally coated surfaces and vertically coated surfaces, than surfaces painted with solvent-based paints
  • Powder coating overspray can be recycled and thus it is possible to achieve nearly 100% use of the coating, which is much more efficient and more eco-friendly than traditional wet painting


Powder coating can be applied on different types of surfaces and materials with or without pre-treatment, such as carbon steel, aluminium, stainless steel or copper. The powder coating process provides an uniform quality and thickness of the powder coating layer, matching the needs for intended product application.

Aztec Nordic Ltd offers powder coating machines for various types of fasteners, including hexagonal, oval, countersunk and low-profile head screws with different types of recesses as well as rivets and bolts.



Master Coat® powder coating enables a perfect color matching of the fastener to the surface it is installed on, including different levels of gloss, metallic effects and special surface structures.
