The drying time of paint depends on the various stages during curing. During the drying process of films various stages are easy to detect but dif­fi­cult to define in terms of chemical and physical principles.

To evaluate these stages objectively it is necessary to use instrumentation under controlled conditions. Drying time recorders in general are available as a single needle circular rotating instruments and as multiple needle linear instruments which has possibilities to set speed adjustments. The track produced by the needle varies according to the degree of dryness.

The various drying stages are defined by calculating the time and track characteristics of the film under investigation. Normally paint is drawn down on the glass panels using a special cub applicator or otherwise by hand. Additionally brass weights may be used to aplly greater pressure on the needles and thus record the through-drying properties of alkyds, varnishes and paints.
