Manganese

Manganese driers are high viscous red – brown solutions of manganese metallic soap with 2-ethyl hexanoic acid in mineral spirits or esters.

Properties

Manganese is a primary drier. Due to its intermediate activity it promotes surface and through drying.

When used alone tends to produce films that are too hard. For this reason it is basically used in enamels in combinations with lead, 

in outside paints and in floor finishes where hard and durable films are required. 

The main disadvantage of manganese driers is that due to their dark colour, they stain or discolour white and light finishes.

Moreover, manganese driers promote initial and long term yellowing. However, the problem of yellowing can be avoided with the use of pale manganese which is lighter in colour.

 In pale manganese the metal is being present in a lower positive oxidation state and its catalytic action is different. 

This product is also the most prominent for cobalt substitution.

Finally, manganese gives good results in low temperatures drying and in high humidity conditions.

 Applications

Manganese is an active drier commonly used in combination with other driers such as Cobalt, Lead and Zinc.

Printing inks drier.

Combustion catalyst.

 EPA (USA Environmental Pollution Agency) tested more than two hundred organic additives for the reduction of the unburned material 

and the total emission of gases in combustion.  

Manganese soap and other metals such as Cobalt, Calcium, Iron and Cerium appear to be the most appropriate combustion catalysts. 

The minimum required additive dosage appears to be 0.5 moles of active metal per ton of fuel.
