On the other hand, dry erase markers make use of an oily polymer variant of silicone.Īpart from this, dry erase whiteboards tend to feature a uniform static charge that allows their pigment to adhere to the board’s surface. Permanent marker inks tend to use acrylic polymer, allowing the pigments to stick to the surface. The prime difference between a permanent marker and a dry erase marker is the polymer used in these two. Finally, resin present in the markers helps the ink retain its shape. However, when working with dry erase markers, make sure you use a mask as the fumes that come from the isopropanol can lead to short-term health issues such as mucous membrane irritation, liver issues, kidney problems, and so on. Further, the isopropanol present in the marker helps dissolve the ink and place them onto the surface. The SD Alcohol-40 can be defined as specially denatured ethanol or ethyl alcohol.
Primarily, dry erase contains isopropanol, SD alcohol-40, & resin. Chemical solvent (alcohol, water, or similar solutions depending on the manufacturer).Permanent markers contain three prime components that include: To understand best how dry erasable marker works, the key is to understand different types of markers, such as permanent markers first. This makes it a superior alternative for writing on white boards.
It is a marker that can be erased from the board as easily as with pencils. It functioned as a great alternative to chalks. These markers came into being in the 1990s era and were paired with boards. But, how are these wonderful markers different from the permanent markers?īefore we dive into the basics, let us get to the history of dry erase markers. The best thing about dry erase markers is the fact that they don’t create a lot of mess when compared to chalk. When was the last time you used a dry erase marker? It was fairly recent, right! Even though we use these markers almost on a regular basis, we hardly know how they work.
