Pre-treatment |
The list of metals and their features explains how raw materials have
natural surface conditions that interfere with coating adhesion and
performance. In the process of being stored, handled and worked they
will pick up additional some contamination on their surface. On
metals, some of the probable contaminants are oily soils including
petroleum products, animal fat, or vegetable oils, deposited during
manufacturing operations for rust protection, drawing, machining and
forming. There may also be heavy duty drawing compounds and
lubrication greases or waxes and some solid soils such as carbon,
graphite smuts, metal shavings, polishing products, metal oxides,
welding scale, die release products, and red or white oxidation.
Removal of soils prior to powder coating is essential to the
successful life of the product. It affects the initial adhesion and
the ultimate performance in the field. Soils that are present on metal
parts can be removed by a variety of mechanical and chemical methods.
What method should be used in a given situation is determined by the
part to be coated (size, configuration, materiel), the type of soil to
be removed (dust, wax, oil, saltcrystals, etc.) and the performance
requirements of the finished product..
