Abstract
In order to produce an optimally smooth paint surface in automobiles, the heating phase of the drying process is interrupted when an object temperature of about 65.degree. C. is reached. This object temperature is then held for at least two and at most three and a half minutes. Then the heating phase is continued until the holding temperature is reached.
Claims19
A method for drying painted automobile bodies or parts thereof which are painted with a one-pack paint in a method having a heating period followed by a holding period at a temperature reached for drying, the method comprising the steps of:
- performing a heating phase exclusively using a pure infrared oven for the paint to be dried;
- and
- interrupting the heating phase for at least two minutes when the paint to be dried reaches a temperature of at least 50.degree. C. and at most 80.degree. C.
