- the two press plates were previously pretreated with the release agent to be tested.
- the separating emulsion was diluted to the specified dilution with water, sprayed onto the metal sheets in a cloister, and then flashed off at 140 ° C. for two minutes for curing. This process was repeated three times.
- the molding was pressed at the specified pressing temperature for 100 seconds.
- the separation behavior after each demoulding was recorded and evaluated as follows:
- the separating emulsion I shows an excellent separating effect, which is retained even at higher pressing temperatures and does not form any deposits on the pressing tool.
- Release emulsion II shows no sufficient release effect, neither at 190 ° C nor at 220 ° C.
- Release emulsion I is effective after a single pretreatment of the sheets over several demolding processes, without the sheets having to be sprayed again after each removal. This offers the manufacturer a certain level of security in the event that the release agent spraying fails during production.
