The Purpose of Coating & How to Measure it.

(This is a General write-up on What is Coating & How it can be Measured to Ensure Cost-Saving Production.)

 What is Coating? 

Coating is known as a layer of a material, typically from Paint, Powder Coating, Enamel, Electroplating or Lacquer, that is applied as a surface of a Base Material, aka Substrate.

 When is it Applied? 

When there is a need to add:

Or for Functional Purpose, on a Substrate.

The Main Consideration of Coating is its Controlled Thickness. 

 When is it Controlled? 

From Application Tools & Equipment like:

• Spray Guns used by Automotive industry to spray on vehicle parts.
• Paint Brushes/Paint Rollers used by Construction industries like painting on Mild Steel Structure.
• Heavy Coating Machineries used by the Electronic industries to coat thousands of electronic parts.

And so on...

 Type of Applicants 

Automotive, Engineering, Electronic, Metal-Fabrication, Furniture, Paint, Electroplating and various related industries that has painting/coating process in their plant.

 Why must it be Measured? 

To Save Cost!
& 
To Meet Technical Requirements!

Those who do not spot-check their coating thickness, may end up with Over-Coated or Under-Coated products.

Over-coated products means that the company will have to spent additional cost than the actual requirement needed by internal QC or accordingly to client's standard.

While Under-Coated products can result with premature failure due to lax of coating thus corrosion will happen earlier than its expected lifespan.

• If noticed, products can be rejected and if rework is required, additional cost will be spent.
• This may affect the company's reputation, for producing 'low-quality' products.

 Coating Measuring Scale? 

The measuring unit to measure coating thickness is usually micrometer (micron/µm) or a thousand of an inch (mil).

Do you think you can do it with:

• a Microscope? 
• With Your Naked Eye?
• With Just a Touch of Your Finger?

Maybe you can, but will it be Accurate or Efficient?

NOT REALLY.

 Our Solution? 

For General Coating Thickness Measurement:

We recommend ElektroPhysik’s Coating Thickness Gauges - MiniTest 700 Series.

The Series provides Non-Destructive Measurement on: 

• Non-Magnetic Coatings (paint, synthetic material, chromium etc.) on Ferromagnetic Substrates (steel). 

• Insulating Coatings (varnish, enamel, synthetic material, anodising aluminium etc.) on Conductive Substrates (aluminium, copper, austenitic stainless steel).
