Permanent markers and whiteboard markers are both used for writing on surfaces, but they have different purposes and compositions:
1. Permanent Marker:
- Permanent markers or Indelible markers, as the name suggests, are a type of marker used to create long-lasting marks on an object.
- Typically, their ink contains carrier solvent, glycerides, pyrrolidone, resins, and colorants to make them resistant to water, fading, and abrasion. Therefore, the marks are difficult to remove.
- Permanent markers are commonly used for labeling items, writing on non-porous surfaces such as metal, plastic, glass, and for creating permanent artwork.
- The ink in permanent markers can be toxic if ingested, so caution is advised, especially around children.
2. Whiteboard Marker:
- Whiteboard markers, also known as dry erase markers, are specifically designed for use on whiteboards (dry erase boards).
- Typically, their ink contains pigment, polymer and volatile solvent vehicle(alcohol), making them erasable that can be easily wiped off with a dry cloth or eraser from non-porous surfaces.
- The ink in whiteboard markers is typically non-toxic and has low odor, making them safer for use in classrooms, offices, and other environments.
- Whiteboard markers are commonly used for presentations, brainstorming sessions, teaching, and other situations where temporary markings are needed.
In summary, the main differences between permanent markers and whiteboard markers lie in their ink compositions, permanence of marks, and intended uses. Permanent markers create lasting marks on various surfaces and are not easily removed, while whiteboard markers produce temporary marks that can be erased from whiteboard surfaces.
