MFFT ( Minimum Film Forming Temperature)

What is MFFT?

Minimum Film Forming Temperature ( MFFT ) is the lowest temperature at which a latex, emulsion or adhesive will uniformly coalesce when laid on a substrate as a thin film. An accurate MFFT value allows the formulation of products that cure correctly under specified application conditions.

How can I check the MFFT is operating at the correct temperature?

Simply place the instrument on range one, allow the platen to stabilise and take note of the temperatures between point 1 and 10. Point 1 should read -5°C and point 10 should read 13°C There should be an even gradient between all points.


Do I need to Calibrate the MFFT?

The instrument operation is governed by precision temperature sensors which are mounted on the reverse of the measurement platen. The output of these sensors is referenced to precision resistors which are extremely stable with time and different ambient conditions

It is because of this the instrument is completely self calibrating and regulating
