This heated perforated vacuum table is made of hard aluminium and anodised in hard-coat flat black to provide a durable and inert surface with an absolute flatness. The surface of the vacuum table is perforated with a grid of small holes which hold the test specimen in position for proper drawdown when attached to a vacuum pump or line. Heated perforated vacuum table is used to create smooth and consistent thin films of paint, lacquers and other materials on sample specimen such as opacity test charts, sample panels, foils or other flat substrates.
- Built-in heating mat allows the temperature of the table to be elevated up to +100 °C above ambient temperature
- Heating device guarantees an even temperature distribution over the entire vacuum plate
- Temperature is set and controlled through a digital temperature controller
Applications: Produce consistent and reproducible test charts for colour comparison, gloss and reflectance testing and other appearance parameters. Apply adhesives, glue and hot melt on test specimen to evaluate bonding strength at different thicknesses and different temperatures. Apply slurries on metal foils for research after new thin film technologies in the battery production industry. Produce reproducible test charts and specimen for scrub-, abrasion- and washability tests.
