Fecha:

Superseeded by:
Significance and Use:

The amount of manganese drier used in oxidizing-type coatings significantly affects their drying properties. This test method may be used to confirm the stated manganese content of pure liquid manganese drier soluble in toluene-alcohol and manufactured for use by the coatings industry.

Scope:

1.1 This test method covers a titrimetric determination of manganese in liquid paint driers that can be dissolved in a toluene-alcohol mixture and utilizes the disodium salt of ethylenediaminetetraacetic acid dihydrate (EDTA).

1.2 This test method is not applicable to drier blends.

1.3 All cations that can be titrated with EDTA in alkaline media interfere and must not be present in the sample.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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.
