Simply stated, a coating consists of a film-forming material dissolved in a solvent. The film-forming material is called a resin. When the resin contains pigments it is called a binder because it binds the pigment particles together and to the substrate over which it has been applied. Pigments are used to add color to the coating and can also enhance the coating's resistance to heat, abrasion and acid. The solvent is present in the coating to make it liquid for ease of application. After application, the solvent evaporates and the binder remains behind.
The chemicals selected to be used for the resin, pigment and solvent influence the properties of the coating in the can, as well as the properties during application and curing. Most importantly, the selection of resin, pigment and solvent will influence how well the coating performs in its intended service environment. For example coal tar resins have excellent moisture-resistance, but poor UV light resistance. Hybrid resins have been formulated to improve the overall performance of resins. In the example of coal tar, it is often combined with an epoxy resin to form coal tar epoxy, which has improved UV resistance relative to an unmodified coal tar resin.
Environmental regulations and safety concerns have had a large influence on the coatings industry in recent years. Legislation limiting the amount of volatile organic compounds (VOC's) in paint has required coating manufacturers to reformulate their coatings to meet environmental regulations. Additionally, the safety concerns associate with such toxic materials as lead and chromate has continuously challenged manufacturers to formulate high-performance coatings using alternative materials.
In this course, the student will study the types and characteristics of commercial coatings.
Learning Objectives
Upon completion of this course, participants will be able to:
- Identify the basic components of a coating system, including the resin, pigment, and solvent.
- Describe resin types, including vinyl, acrylic, epoxy, phenolic, and urethane.
- Explain the function of drying oils and compare the relative merits of each type.
- Identify the purposes and types of pigments, including inhibitive, sacrificial, hiding, color, and extender pigments.
- Compare different solvent types and their relative merits.
- Describe the functions and types of miscellaneous additives, such as antiskinning agents, fungicides, emulsion aids, and flow agents.
- Compare the types of zinc-rich coatings and their relative merits.
- Explain the impact of VOCs on coating manufacture and selection.
