INDUSTRIAL MACHINERY ENAMEL is a modified alkyd enamel which forms a weather resistant coating.It is felexible and resistant to salt and spillage of mineral oiland other aliphatic hydrocarbons.As a general purpose finishing coat in alkyd paint systems in mild to moderately corrosive environment. Alkyds are modified with large number of other resinous materials, and this is one of  their distinct advantages. each of the other resins provides some of its properties to the alkyds and, in doing so, makes for a versatile series of coating materials. The primary materials that can be combined with alkyds are listed below.
Some, but not all of these combinations are of interest to the corrosion engineer. Most of these materials are actually reacted into the basic alkyd resins and are considered copolymers. They usually have increased corrosion-resistance when compared with a pure alkyd, depending on the modifying resin. The following alkyd modifications will be taken up individually.
