The Future of Protective Coating

While the use of protective coatings is becoming more and more important to prevent the metal from degradation due to corrosion, there have been change drastically both paint and the protective coating industries. 

Environment become more extreme such as air pollution, hazardous waste disposal etc. followed by rate of corrosion also increase, existing protective coating need to be improved to protect the metal from extreme environment. 

The variety of materials within a coating and the in-numerable conditions under which it must performed thus give rise to hundred of different types of coatings. Each variation is developed to address differences in material, application, or use. Todays concept " anyone can paint and brush" was obsolete. Coating are vital to protection of all types of structure used by society which are, in themselves, becoming more complex and subject to increasingly more corrosive environments. Thus, coatings are becoming so vital to their protection that they should be considered an actual part of the structure and not simply a last-minute detail.

Even more variables are introduced by the drying process. Industrial product finishes have been developed to limit many of the draying variables by controlling the type of application and the speed and temperature at which the coating is cured. Unfortunately, most industrial coatings are applied to structure where the curing of the coating cannot be accurately controlled. This is usually due to variables such as weather, humidity, surface condition, the type of substrate, surface cleanliness, application technique. It may also be necessary to deal with a rather wide variety of coatings, which often dry in radically different ways, affecting the final film.
