When we grab a Sharpie and make a mark, we rarely think about what chemicals are inside. But have you ever wondered what makes a Sharpie so permanent, so indelible? The answer lies in the special blend of chemicals that make up a Sharpie ink.
Sharpies are made with a blend of solvents, pigments, and resins that create a formula ideal for writing, drawing and coloring. The solvents are volatile and quickly evaporate, leaving behind a pigment residue that is resistant to fading. The pigments are composed of organic compounds that are insoluble in water and oil, which means they do not dissolve or break down easily.
But what about the resin? The resin helps to bind the ink to the surface, making it more permanent and water-resistant. Sharpie inks do not contain any acids, which makes them safe to use on a wide range of surfaces without causing damage. Although the exact composition of Sharpie inks can vary depending on the color and type of pen, they typically contain a blend of xylene, toluene, and ethanol.
Chemical composition of Sharpies
Sharpies are a popular brand of permanent markers that are commonly used for various purposes, such as labeling, drawing, or writing. The markers are formulated with various chemicals that contribute to their unique characteristics, such as fast drying, waterproof, and resistant to fading. The chemical composition of Sharpies can be broken down into several key components, including:
- Resin
- Solvent
- Pigment
- Additives
The resin in Sharpies is typically made from a blend of polymers that provide the markers with their permanent ink properties. The resin is what binds the pigments to the surface and makes it resistant to smudging or rubbing off.
The solvent in Sharpies is responsible for making the ink flow out of the pen and onto the surface. The solvent also facilitates the rapid drying time of the ink. The solvents used in Sharpies are typically alcohols, such as ethanol, propanol, or isopropanol.
The pigments in Sharpies are what give the markers their various colors. The pigments used in Sharpies are usually organic or inorganic compounds that are finely ground and dispersed throughout the resin and solvent mixture. Some of the common pigments used in Sharpies include carbon black, lead chromate, and phthalocyanine green.
Finally, additives are used to enhance certain properties of the Sharpies. For example, UV absorbers are added to protect against UV light degradation, while surfactants are added to improve the flow and wetting of the ink on the surface.
