filler pigment
Quick Summary
Pigments are insoluble particles that provide color, opacity, and other properties to coatings, while also reducing costs by acting as fillers. They range in size and composition.
There are three main categories:
* Color pigments: These absorb certain wavelengths of light to create color. Examples include blues, greens, reds, and yellows derived from organic and inorganic compounds.1
* Filler pigments: Also known as extenders, these primarily add volume and enhance mechanical, thermal, and barrier properties without significantly affecting optical qualities. Common examples include talcs, calcium carbonate, silicas, micas, and clays.2
* Specialty and functional pigments: These offer unique optical effects (like metallic or pearlescent finishes) or provide specific chemical functions such as corrosion inhibition, mildew control, or fire retardancy.3
