Moisture Measurement

Moisture: The presence of moisture within a material will result in poor adhesion, premature coating failure and poor appearance. For example, applying a powder coating to a damp wooden panel will cause steam to be created when the panel passes through the curing oven, thus causing damage to the coating.

It is not sufficient to simply ensure that the surface is dry by touch. The surface of the substrate is often the driest point due to evaporation. It is important to establish the moisture content within the substrate itself. The moisture measurement can either be taken using a Pin moisture meter or Pinless (Contact-Type) moisture meter.

Elcometer Guide to Climatic Testing

Monitoring climatic conditions, such as temperature, relative humidity, dewpoint and moisture, is often vital to the successful application of a coating and is critical to the resulting quality and performance of the coated product.
