MFFT tester MFFT 90

temperatureminimum film forming temperaturefor paint

Summary
Measures the minimum film forming temperature (MFFT) of water‑based coatings, including latex, emulsions and adhesives. Operating range -10°C to 90°C. Platen dimensions 483 mm × 235 mm. Integrated air drying system and water cooling. Manufacturer: Paintlab.

Applications

• Paints & coatings: determines the lowest temperature at which a thin film will uniformly coalesce (test methods based on ASTM D2354 and ISO 2115).
• Adhesives: assessment for one‑pack adhesives; for two‑pack systems use of a foil strip can ease cleaning and allow determination of minimum cure temperature.
• R&D, quality control and production sampling for emulsions, polymers and coatings.

Operation
Select the required temperature program and allow the instrument to reach thermal equilibrium. Apply wet test tracks using a cube applicator or spreader across the platen gradient. After drying or curing the MFFT is determined by visual inspection of the film appearance along the platen.

Standard features
Standard model MFFT-90 with ten temperature programs; integrated air dryer with flow controller; sintered metal distribution block for uniform gas flow; quick‑release water couplings; hinged viewing cover; audible and visible alarms for cooling water protection.

The MFFT method
A dull nickel‑plated copper platen is cooled at one end and warmed at the other while a uniform flow of air or nitrogen moves from the cold to the warm end via a sintered metal distribution block to ensure even drying and avoid inlet freezing. The integrated air dryer contains indicator crystals visible in a transparent container. Water at mains pressure removes heat from the coolers; a chiller/recirculating unit is available where inlet water temperatures are high. Temperature sensors along the platen provide program control and indication. A hinged viewing cover provides thermal insulation while permitting visual inspection.

Safety notes
Use may involve hazardous materials and procedures. Users must establish appropriate safety and health practices and confirm regulatory applicability before use.
