Definitions
- the invention relates to a method for drying with two-component paint painted automobile bodies.
- the holding temperature is already after 20 to 30 Seconds reached. Since the holding temperature for conventional top coats is over 100 ° C, this means that heating takes place at a speed of approx. 200 ° C. per minute. A to heat up the entire vehicle body in such a short time at this speed, is technically almost impossible. This burns the paint surface and creates Stoves that lead to craters. A perfect paint surface can be applied to this Way not reach.
- the object of the present invention is to remedy this to create and a process for drying with two-component paint painted vehicle bodies or parts propose of which with which an almost level Paint structure is generated without additional effort.
- the heating phase begins at ambient temperature of approx. 15 ° C and will be until a Operating temperature of 150 ° C continuously. For this Heating time until reaching 150 ° C is a maximum of 6 Minutes needed. This means a heating up of approx. 20 ° C per minute.
