Testing methods & instruments for vitreous (porcelain) powder enamels

To maintain the reproducibility of the coating quality at your enameling plant, it is important to monitor and control all major process parameters.

With regard to the electrostatic powder enamel application department, it is necessary to keep your ambient conditions, equipment settings and powder properties within strict tolerances.

Powder enamel properties

The properties of powder porcelain enamels may be characterized by the following parameters :

  • Adhesion
  • Application rate
  • Fluidity
  • Particle size distribution
  • Surface resistivity
  • Powder resistivity is an important parameter at electrostatic powder coating operations. For this reason it is highly recommended to verify the resistivity of powder paint and/or powder enamels regularly. Features & benefits Accurate & repeatable resistivity measurements Easy to operate & clean Suitable for powder paint & powder enamel...

  • Adhesion tester for electrostatic powder enamel - Improved design for better clamping - Supplied complete with evaluation software

  • Industrial fluidity meter, suitable for powder enamel and powder paints.It is well known that powder suspension, transport & spraying depends on many factors, like particle size, humidity & powder formulation.This device is specially designed to qualify the suitability of powder paint or powder enamel for spraying at quality control laboratories...
