Paint Analysis

Dye analyzes are performed to look for differences between known and questioned samples for many purposes. However, even in samples known to be from the same source, there may be differences in appearance, layer order, size, shape, thickness, or some other physical or chemical properties.

Test methods such as wet paint, dry paint film and performance tests are applied by the manufacturers in order to offer paints with the same physical and chemical characteristics to consumers every time with the properties described on the label. In this context, paint covering power, density, viscosity, adhesion strength, drying speed, hardness, color control, elasticity, resistance to chemicals and aging tests are carried out in advanced laboratories.

These test methods are based on international standards. Manufacturers also implement a quality assurance program that includes proficiency tests and technical audits for reporting analytical test procedures and results.

For the purposes of the applied standards,

• The term binder refers to the non-volatile part of the liquid carrier of the coating that serves to bind or adhere the pigment particles together.
• Coating is a general term for paint, lacquer, enamel or other liquid or liquefiable material that is converted after application into a solid, protective or decorative film, or a combination of such films.
• The term paint generally refers to a pigmented coating.
• The term pigment refers to a finely ground, inorganic or organic, insoluble and dispersed particle. Besides color, a pigment provides many of the essential properties of paint, such as opacity, hardness, durability and corrosion resistance.
• The term additive refers to any substance added in small amounts to improve properties.

Paint films are characterized by a number of physical and chemical properties. Physical properties include colour, layer order and thickness, surface and layer properties, contaminants and weathering. Chemical components include pigments, polymers and additives. These properties are determined and evaluated by various macroscopic, microscopic, chemical and instrumental methods. Limited sample size and sample preservation requirements require these methods to be selected and applied in a reasonable order.
