Gradient Oven Model 432

The Model 432 gradient oven is used to evaluate the baking and drying behaviour of paint and powder coatings, resins, plastics, and similar materials. It can simulate a production process by programming the warm-up rate, burn-in temperature, and time intervals. It allows predictions of how a particular paint reacts to a particular material at different temperatures. The excellent repeatability of the measurements allows a remarkably accurate determination of the actual limit values. Depending on the type of oven, coatings can be tested up to a temperature of 320 °C. If the lacquers are applied with a double doctor blade, two different lacquers can be tested simultaneously on one test sheet.
