Standard Test Method for Minimum Film Formation Temperature (MFFT) of Emulsion Vehicles

Fecha:
2013-03-06 /Historical
Superseeded by:
Significance and Use:

The satisfactory film integrity of emulsion coatings requires that as the aqueous phase evaporates the resinous portion of the vehicle coalesces into a continuous film. Low temperature impairs the fluidity of the resin particle and thereby their ability to coalesce. Vehicles that can withstand low temperatures are therefore required, and MFFT is an important quality feature of emulsion vehicles.

Scope:

1.1 This test method covers the determination of the minimum temperature at which emulsion vehicles coalesce to form continuous films. The term emulsion in this test method includes latex vehicles.

1.2 This test method is limited to emulsions having minimum film formation temperatures below 90°C.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
