Coatings are applied to many substrates from metal (hard) to skin (soft). Application surfaces define the performance and quality of the products. Substrate performance needs demand that different raw materials be used to deliver the needed product. This article is a general review of the development of coating manufacturing processes, but also discusses and outlines how to simplify and improve manufacturing processes.
A review reveals that processing methods are similar for most of the coatings even for different processed components. It is interesting to follow the path of how the coating manufacturing processes developed. Powder Coatings have been excluded.
In general there are two types of liquid coatings.
1. Water based
2. Solvent based
Coatings components that are needed to meet specific performance can be classified in the following general categories.
* Solvent (water or organic)
* Pigments/Fillers
* Resins
* Additives such as Thickeners/ Surfactants/Dispersants/Preservatives/Flavors
* Colorants
