Mandrel Bend Test
Physical bending test for evaluating flexibility of a coating.
Masking
Covered area of a part to prevent coverage by powder during application.
Masking Tape
An adhesive tape made for easy application and removal to mask areas where coating is not to be applied.
Material Utilisation
The percentage of powder that actually is deposited on the parts.
Maximum Loading Density
The maximum number of parts that can be loaded onto a conveyor to ensure maximum powder utilisation.
Melt Mixing
A predominant process for the manufacture of powder coatings involving continuous compounding of pigment, resin, fillers, additives and hardeners, mixing at elevated temperature.
Melting Point
The temperature at which a finely divided powder will begin to melt and flow.
Membrane
A fine (usually porous) substance separating adjacent parts equipment.
Metamerism
A visual characteristic that describes a coating that appears different in colour when viewed under different lights.
Micron
One millionth of a meter. Used to express applied film thickness.
Mil
One thousandth of an inch. 25 micron equivalent used mainly in the USA.
Mild Steel
Structural Steel or plate malleable iron based alloy. SEA 1020 with a carbon content of up to 2.5%.
Mileage
A term used to describe the area covered by a given amount of powder, usually measured in "square meters per kilo" or "pounds per square foot".
Mill Scale Oxide
layer formed on the steel by hot rolling process.
Miscible
Capable of mixing or blending.
Misses
Voids in the cured coating.
Molecule
The smallest particle of a substance that can exist and still retain the properties of that substance. Molecules consist of two or more atoms.
Monomer
A molecule that can be chemically bound as a unit of polymer.
