Powder Coatings

The custom powder coating was first introduced in Australia. Powder coating is a form of dry coating, which is employed as a free-flowing, dry powder.

Powder coating systems produce high specification coating which is comparatively firm, abrasion resistant and hard. There are two types of powder coatings available that are: thermoplastic powders and thermosetting powders.

Powder coating metal can become easier by preheating the object that may assist to achieve a more uniform finish.
