Pens with erasable ink

Erasable ink

— pens with erasable ink are called “write-erase”. The ability to erase a previously made recording allows you to accurately correct the mistakes made. There are many varieties of erasable ink pens, which can be broadly classified into three types: heat-sensitive, solvent, and with an eraser.

Heat-sensitive write-erase pens – the ink becomes colourless when exposed to elevated temperatures. Such inks have high adhesion and penetrate deeply into the paper. If you rub the inscription, thereby creating an elevated temperature, the ink will become transparent. The same will happen when heating sheets of paper with a hair dryer.

Pens write-erase with a solvent – the records are erased when a special reagent is applied. As a rule, a marker rod impregnated with a reagent is inserted into the cap or on the back of the pen. It is enough just to dip the marker on those parts of the text that you want to erase. The processed part of the text will dissolve without a trace within a minute. Nowadays, write-erase pens with a solvent are the most effective, they are widely used.

Pens write-erase with an eraser – the ink has surface adhesion, by analogy with simple drawing pencils (graphite rod). To erase the record, you just need to use the eraser that is built into the cap or the back of the pen. Pens with erasable ink of this type are the most durable. Of course, it is not recommended to make any responsible notes with such pens, since some of the parts of the record can be smeared or overwritten by chance.
