pigmendipõhised

Pigmendipõhised refers to materials or substances that are colored using pigments. Pigments are insoluble coloring agents that are dispersed within a medium, rather than being dissolved in it like dyes. This distinction is important because it affects how the color is applied and its properties. Pigments provide opacity and durability, making them suitable for a wide range of applications.

In the context of paints, pigments are finely ground solid particles suspended in a liquid binder. This binder, along with other additives, forms the paint film once the liquid evaporates. The choice of pigment determines the color, hiding power, and lightfastness of the paint. Common examples include titanium dioxide for white, iron oxides for reds and yellows, and carbon black for black.

Beyond paints, pigmendipõhised materials are found in inks, plastics, cosmetics, and even building materials like concrete and tiles. In each case, the pigment is physically mixed into the base material. This physical dispersion means that pigments can settle over time if not properly formulated, and their particle size and shape can significantly influence the final appearance and performance of the product. The inert nature of many pigments also contributes to their resistance to fading and chemical degradation.
