Whiteboard coating is a type of paint that can be applied to surfaces to create a dry erase board. The exact chemical composition of whiteboard coating can vary depending on the manufacturer, but it typically contains a mixture of resins, solvents, and additives.

The resins used in whiteboard coating are typically acrylic or epoxy resins. These resins are chosen for their ability to form a hard, durable film that can withstand regular use and erasing. Solvents are added to the coating to help dissolve the resins and make the coating easier to apply. Common solvents used in whiteboard coatings include water, ethanol, and glycol ethers.

Additives are also used in whiteboard coatings to improve the performance of the coating. These can include surfactants to improve the wetting and flow of the coating, pigments to provide color, and fillers to improve the hardness and abrasion resistance of the coating.

In summary, whiteboard coating typically contains a mixture of resins, solvents, and additives, which work together to create a durable, easy-to-clean surface that can be used as a dry erase board.
