Dry markers are a kind of magical thing. On a surface, they easily leave marks on, but then you can wipe it away, leaving virtually no trace behind. The process is dry as it does not involve any liquid to clean up. In the mid-1990s to serve as an alternative for chalk dry markers and boards came into existence. Dry erase markers never make as much of a mess as chalk does, and the sound that the chalk on a chalkboard makes is also not seen in these markers.
But, what is the one thing about dry erase markers that sets them apart from permanent markers? The ink is prepared of color pigments which are a chemical solvent and a polymer or release agent. The type of polymer used is the main difference between dry-erase markers and permanent markers. Permanent markers make use of an acrylic polymer that helps in sticking the pigment to the surfaces, whereas dry markers China makes use of an oily silicone polymer.
If you go one step further then you will get to hear about wet-erase markers. Compared to dry erase markers these are quite different. You can use wet-erase markers on non-porous, or acetate surfaces. In removing wet-erase markers a wet cloth can be used. On the other side, with just a simple swipe of dry erase markers you can erase anything.
For certain signs, restaurants and stores can even opt to use wet-erase markers because they allow for a more permanent text that will not be erased if someone accidentally bumps against a sign. Generally dry erase markers are used for text by dry markers manufacturer that needs to be frequently changed. It’s also important to note that to remove chemical build-up that is caused by markers, regular cleaning of whiteboards is necessary.
Hence, polymer science is involved in so many things than we could ever imagine including markers and thousands of other objects that we cross paths with every day. You can use wet-erase markers on non-porous, or acetate surfaces. In removing wet-erase markers a wet cloth can be used.
