Minimum Film Formation Temperature Tester

Standards: DIN 53787 - DIN 53 366 – ASTM D 2354 - ASTM D 1465 – ISO 2115 - ISO/DIS 4622

Gradient Tester for:

  • Minimum film forming temperature, white point/glass transition temperature of dispersion materials, synthetic resins, enamels ...
  • Blocking power and stacking capability of coated papers, foils, prints...

Test instrument with a ground hard-chrome plated metal plate as a measuring plate for depositing the specimens. By heating and cooling the measuring plate any variable temperature gradient within the range of -30°C to +250°C can be produced and kept constant for any given period.

The measuring plate is equipped with 20 temperature sensors. The temperature can be controlled by the integrated electronic temperature measuring instrument with a digital display and measuring-point selector over the entire range.

To determine the minimum film forming temperature "MFT" the specimens are applied to the measuring plate by a film coating appliance and protected from ambient air by a covering cap.

To determine the blocking power the specimens on the measuring plate are weighed by defined loads to simulate the stacking capability.
