Powder Thickness Measurement
Uncured

A powder coating has many advantages over a wet coating system, including:
  • Little or no waste – excess powder or oversprayed powder can be recycled and reused.
  • No solvents – tighter environmental controls of VOC emissions and legislation increases the need to use less or no solvents.
Making sure that the end product has the correct levels of adhesion and appearance - in particular gloss and colour – is dependent upon the thickness of the powder prior to the curing process, and the temperature profile of the oven.

Measuring the thickness of powder however, is difficult as touching it changes the powder thickness compressing it under the force. Elcometer have therefore developed two solutions to this problem.

Elcometer 155 Powder Comb

Elcometer 155 Uncured Powder Comb

The Elcometer 155 Uncured Powder Comb is available in four scale ranges, the Elcometer 155 is designed to measure uncured powder coating film thickness. This enables the application system to be set up and fine tuned prior to the curing process. In turn, this will reduce the amount of scrap and over-spray. Place the comb into the powder and slide the comb towards you. The powder comb should be used as a guide only. Range : 50 to 1250 mic.

Elcometer 550 Non Contact Powder Thickness Gauge

Elcometer 550 Non Contact Powder Thickness Gauge

The Elcometer 550 Non Contact Powder Thickness Gauge offers the user an unrivalled approach to measuring uncured powder thicknesses - without touching the powder . By measuring the powder density as opposed to powder thickness, the gauge is designed to provide the user with the correct value of the cured film thickness, by the measurement of the uncured powder thickness, enabling the application system (powder guns, line speed, etc) to be set up and fine tuned. Range : 30 to 110 mic. Accuracy : 5 mic. Conforms to ASTM, D5101
