Powder Coating  
  Powder coating, sometimes called dry paint, is well suited to today¡¦s requirements for quality finishes that are environmentally friendly. It offers the designer a wide array of colours, durable finishes, and other specifications. Different powders are available in a range of costs and quality. We are currently using Dulux and Akzo Nobel from Australia and their wide range of colour can be found at their website:

To ensure the applied powder coating will meet the specified performance requirements, there are on-site tests to be performed as:

Solvent cure test - Usually straight MEK or a less aggressive solvent is applied to the powder coated part and resistance to the solvent is used to evaluate the degree of cure.

Adhesion test - Cross Hatch tape pull test to evaluate the powder coating adhesion to the substrate.

Thickness - Testing instruments to accurately measure dry film builds. This is essential to ensure proper film builds are being applied.

Permeability - Usually for exterior applications, finished sample is placed in a pressure cooker with water, testf for adhesion.

Impact test - Evaluates powder adhesion and flexibility.

Hardness - Pencil hardness test evaluates powder hardness and cure.

Colour and gloss - Matched to coating supplier¡¦s standard panels.

Visual finish appearance - inspection of colour, gloss, flow, edge, coverage, texture etc. to powder coating suppliers standard.
