The powder coating process produces protective and decorative coatings for a range of surfaces. It has applications across different industries and sectors, such as manufacturing, architecture and automotive.
With a broad scope of applications, there are requirements for different types of powder coating finishes, including glossy finishes.
Applying powder coating is a process involving three parts:
First, the surface that you wish to coat requires cleaning and pre-treatment
The powder coating adheres to the surface it is applied to through the spray-gun’s electrostatic charge. This application enables a uniform covering, even where there are tight corners or sharp angles.
Then, under heat, the powder coating melts and fuses together, hardening into a uniform shell.
The final finish of this shell will depend on the type of powder coating you apply.
Because powder coatings combine resins, fillers and pigments, they come in a range of colour shades, and these shades are available in a choice of gloss level.
You can use powder coatings both indoors and outdoors across a range of gloss levels. But what determines how glossy a powder coating finish is?
There are several factors which affect gloss levels:
Generally, using fillers in powder coating that have very small particle sizes will achieve high gloss levels.
As particle sizes increase, the gloss level drops.
You can fine-tune of gloss levels in powder coating through the choice of fillers, such as barium sulphate and ATH (aluminium trihydrate).
What Are the Gloss Levels of Powder Coatings?
Powder coating colour shades are available in different gloss levels:
These levels will vary depending on the individual powder coating manufacturer.
Powder coating continues to grow in popularity as a finish for external and internal surfaces.
Depending on the location and end-purpose of the coated material, glossy finishes can add a distinctive decorative touch.
At the same time, this decorative aspect of powder coating does not detract from its all-round durability and practical benefits as a protective coating.
Powder coating also has these benefits:
