Coatings raw materials can be grouped into four broad categories of chemical constituents :Resins: Polymers either dissolved—or
carried—in water or organic solvents Pigments: Both chromatic (“primary pigments”) and extender, filler, flattening, etc. (“secondary pigments”)
Solvents: Organic—water is not discussed in this article Additives: Rheology modifiers; surfactants; dispersants; biocides; coalescent ; catalysts;
deformers; adhesion promoters; and a host of other specialized chemical constituents typically used at very low levels, as a percentage of the
formula weightEpoxy polymers (resins) Epoxy resins are often used as the binder in industrial coatings (primers). They give the paint excellent
adhesion together with high resistance to chemicals (corrosion), and physical resistance necessary, for example, on ships and chemical storage tanks.
Powder coating creates a high-quality finish on surfaces that is more durable than paints. Here's how you can incorporate it in your next chemical
