Minimum Film Forming Temperature (MFFT)

The Rhopoint MFFT is the industry leading instrument for measuring the minimum film forming temperature of water based materials. Definition - “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.

The Rhopoint MFFT works by holding a very accurate temperature gradient across a nickel plated copper platen. A flow of dried air across the platen stops condensation forming and gives repeatable test conditions.

Specification

Paints and Coatings
The minimum film-forming temperature (MFFT) of a paint or coating is the lowest temperature at which it will uniformly coalesce when laid on a substrate as a thin film. The standard test for determining this temperature involves using a MFFT-BAR, as specified by such standards as ASTM D 2354 and ISO 2115. The design of the Rhopoint instrument is based directly on these standards.

Adhesives
The MFFT of one-pack adhesives can be found in a similar way to paints and coatings. With two-pack adhesives, a strip of aluminium foil can be laid on the platen, to ease cleaning, before applying the adhesive. Two-pack adhesives do not show an MFFT, but the minimum cure temperature can be found by scraping the sample with a spatula
